I also think the actions taken by tech companies here reflects a double-standard. For example, why isn't AOC being blocked for supporting rioting? Why weren't Democrats called out for attacks on federal property in Portland, Seattle, and other cities? Look at https://thefederalist.com/2021/01/07/aocs-comms-director-ask... for an exploration of this.
To me, it just looks like big tech companies picking winners and losers in an ongoing political and cultural war, and are reacting to societal or political pressures in taking action rather than acting in any principled manner.
