Have you asked them why? I'd be willing to bet that it's because of vendor lock-in if you boil down to it. Lots of things only work on Chrome. Video calls are especially prevalent right now, but there's a bunch of bot detection shit that only works on Chrome too.

Yes and IIRC it was not due to any forced factor, just because they considered it better.
