We're in such a shitty timeline right now where these CEO's realize that they have so many mainstream users who just don't actually care about the platform and just want the content, that even with significant controversy if they just ignore it, they can almost certainly weather the storm. Sure, their platform will be worse off, they'll lose users to other platforms, but it's a far cry from the Digg v3 -> Reddit situation when there was a much smaller user base who was more passionate about the site and community and they abandoned the old site as a result of those shitty decisions.
