It seems that they are doing it everywhere on their website, also in most of their recently started projects.

Ironically, while looking into it, I found that one of their projects seems to use generative AI to make it work.

It might be because of what you said, though the same way I asked an LLM to insert proper uppercasing I can also ask it to remove it. So it would be more for the "vibes" more than anything.
