The responsibility starts to fuzz when you try to follow that thread.
It's clearly with the company executing the decision to remove someone from their platform, but trying to decipher whether or not what they're doing is a financial or moral decision (despite their claims, that's part of the financial choice) becomes fairly pointless.
If you want to rail against a changing society, that seems like a waste of time. If you want to rail against a specific set of companies who have acted in a specific way, I think that's more productive and addressable.
