Well, the reason for the replacement seems pretty obvious: they're shipping new features on the web that aren't matched by the native client, and apparently that was just too hard to update for a multibillion AI-powered behemoth. So, a wrapper it is!

You may not like that from a 'native look and feel' point of view, but the question 'what is a native Windows app these days anyway' is very much unanswerable, and you can actually implement stuff like this in a performant and offline-sensitive way.

But, yeah, by the time the resulting GPU worker process balloons up to 400MB, that pretty much goes out of the window. I'm actually sort-of impressed, in that I have no idea how I would even make that happen! But that's why I don't work at a powerhouse like Meta, I guess...
