Jerusalem has a long-standing theological significance in Islam: it was originally the target of Muslim prayer (the qibla), until Mecca replaced it; Quran 17:1 mentions Muhammad’s supernatural “Night Journey” to the “Farthest Mosque”, which Islamic tradition identifies with the Temple Mount in Jerusalem. Sunni eschatological traditions also mention Jerusalem as having a role to play in the “end times”.
Aside from theology, Jerusalem also has a great historical significance, in that its reconquest from the Crusaders was considered an important turning point in global Islamic history. Given its position in-between Egypt and Syria, control of Jerusalem has been contested between competing Islamic empires many times over the centuries
By contrast, Xinjiang has no established theological significance in Islam, and its history is a footnote in the overall history of Islam
Also, it wasn’t just Jewish people who lived in what is now the territory of Israel in ancient times - it always had a significant population of polytheists (Canaanite, Phoenician, etc), plus two thousand years ago the Samaritans were a massive community of military significance, not the tiny minority they are today. Most of its non-Jewish population converted to Christianity - along with a significant chunk of its Jewish population. And then when Islam came along, the majority of its Christian population converted to Islam (a slow process over many centuries). Arguably, Palestinians are just as much descendants of its ancient population as Jews are, indeed, Palestinians are likely in part descended from Jewish converts to Christianity and Islam.
As did other dominant groups before and after them. In any case the Jewish population's size and influence peaked after a major catastrophe (the Bar Kokhba revolt) some 500 years before the first wave of Islamization even reached the region.
Isn’t this just manufacturing an artificial claim?
What they did was no different from the inevitable self-imprinting both religious movements and settler groups do in places the get traction in - they started to believe in a part-mythical, part factual "origin story" of how they got there and assumed dominance, and that was that. In essence no more "artificial" from the imprinting of any other group that attains dominance in a region over time (including that of the Jews in the area, many centuries previously).
Islam's telling to itself seems to go about like this:

By way of context: (1) it took a long time for this to happen (specifically in two waves about 550 years apart), and (2) even by the first wave, the Jewish community had already been vastly diminished (in part by expulsion, in part by assimilation as the other commenter notes), and the region had already been long since Christianized.
So there was no major Jewish imprinting to dismantle or oppose by then - or even make reference to, by then. If anything (with Christianity's imprint melting away before them) the region probably started to appear as a tabula rasa to them, in short enough order.

The Farthest (Al-Aqsa) Mosque being in Jerusalem is a recent invention. The night journey is said to have happened in 621, but the Al-Aqsa Mosque was built in 637 when the Muslims captured Jerusalem. So the Al-Aqsa Mosque of the Quran is not the one currently called the Al-Aqsa Mosque.
Do you have any evidence that Muslims have only "recently" started to claim it is in Jerusalem? From what I understand, they were already claiming that well over 1000 years ago.
> The night journey is said to have happened in 621, but the Al-Aqsa Mosque was built in 637 when the Muslims captured Jerusalem. So the Al-Aqsa Mosque of the Quran is not the one currently called the Al-Aqsa Mosque.
Standard explanation for this: "Al-Aqsa Mosque" has two senses, a broad sense and a narrow sense. In the broad sense, it is the entire complex of Islamic religious structures on the Temple Mount, centered on the Dome of the Rock. In a narrow sense, it is the main congregational prayer hall in that complex, the current building of which was constructed in the 1030s. The 637 structure you mention was a temporary wooden structure, which by the next century was replaced by a much grander stone one, which went on to twice be destroyed by earthquakes.
So, since in the broad sense "Al-Aqsa Mosque" means the whole Temple Mount complex, of course the Temple Mount pre-existed the Islamic conquest of Jerusalem in 637 (around 5 years after Muhammad's death), and it was there for Muhammad to have supernaturally visited in 621 (if one believes he went on such a supernatural journey, I personally don't)
Indeed, according to many Muslim accounts, the site Muhammad visited in 621 was not the site of the narrow sense mosque, it was the rock which the Dome of the Rock now covers.
The Arab-islamic world is made up of autocracies; they don't need to care about a lot, and they indeed showed extremely little concern for the Palestinians as well.
Regarding organ harvesting, the FBI arrested Israeli-connected illegal organ harvesters in the US, as reported by the New York Times. The Palestinians have complained about Israeli organ harvesting, and apparently the US is concerned about their illegal organ harvesting networks too.
For the second, I don't know anything about it
For the Uighurs, there are allegations of 25.000 murders a year for organ harvesting in the Xinjiang.
