Also possible Blizzard asks their more senior people to do these AMA's I guess...
Yes there are still people working for Blizzard that have been there for 15 years or longer. (Is that a good thing? yes and no. The motivation declines the longer you are at a specific job, not that it applies to everyone but I consider that to be a a big factor)
The issue here though isn't about how long someone has been working on a project like WoW or for the company itself. The main issue is that like any other company out there that became successful it went in full corporate mode.
That dev that has been working in wow since 2002 and before the game was even out, has probably very little say of what happens to the game. The game as any other game that is coming out from blizzard right now feels like its build by pure stats. It feels like a marketing specialist, sat down with a stats guru and they decided on what people like based on trends and what people are doing. That combined with the business people demanding more money, more game currency transactions, more gambling involved into the game and RNG being the top, have made games like WoW being awful to enjoy.
The difference between Blizzard back then and Activision-Blizzard now is that Blizzard a small/medium game studio was building games that the team would love to play. WoW was a pure unexplored world ready to accommodate any kind of player - it was an adventure. Nowadays the WoW of today is like a themepark where every ride is very specific.
Again personally I spent so much time in WoW during the first 2-3 expansions, and nowadays I want to play but the game is just not good enough.
So as a player yes I'd say you are right to say there are people still working for Blizzard that were working back then but the small/medium studio that would put passion behind their games, turned into a corporation trying to build games based on stats.
And I hope that there will be another indie company that will eventually become like valve, blizzard or ea. Us gamers need that, we need a company that will produce amazing games with loads of passion and not just for the moneygrab.
The other argument is that Blizzard tends to do remastered releases of games ~15 years after their original release, and guess what, it's been 15 years. So it fits into that bucket as well.
While it's definitely a grab at more players, people are also asking for it. Go poking around to see how much people are excited about this thing (there are various podcasts, https://countdowntoclassic.com/ being one I've listened to).
Like who you replied to, i sort if blame activision for the death of blizzard, but that timeline doesnt really line up. I wonder whats going on? Changing demogrpahics, I suppose.
Similarly, Burning Crusade and Wrath of the Lich King are pure Blizzard. Cataclysm (2010) was controversial. On the other hand Mists of Pandaria (2012) was generally disliked, Warlords of Draenor (2014) was an inane mess.

[4] “The precursors to modern-day heirlooms were introduced in Vanilla/Classic World of Warcraft. Heirlooms up to the Wrath of the Lich King expansion were items that were sold by a specific battleground vendor. There were Warsong Gulch, Arathi Basin and Alterac Valley heirlooms.”
[2] This depends on how you mark an expansion. IMO, after the initial bug fixes are put that’s the expansion. Everything after that like 3.3.0 is it’s own separate patch.
Regarding heirlooms, they were introduced in WotLK:
"Heirlooms that increase experience and scale based on character level were introduced in the Wrath of the Lich King expansion."
The line is blurry, but I believe that a trend was definitely noticeable even in late Burning Crusade. In particular, efforts to attract a broader player base. It is unfortunately surprisingly hard to track and timestamp all the controversial changes introduced to the game.
Legion went through the same thing where at the start it was considered even worse than Warlords, but is now considered a high water mark.
I assume people that remain generally liked the changes, but from what I can tell the player base tanked.
For some people, there hasn't been a great traditional Blizzard game in many years.
