I take a middle position on this having seen it all at Twitter since 2006. The site does still work, but not without outages. Of course, Twitter had major outages during the Williams/Costello/Dorsey period as well. What happened was that when Musk obtained control, the haters claimed that Twitter/X would burn down or get bricked. None of that ever happened, which leads some people to believe it "still works fine" with 20% of the former staff.
