#StrawMan: nobody claimed that every Facebook/Instagram user is a bad person. The argument is that the company is evil and has evil policies and will do evil things based on a long history of doing evil things.
"and I want to be able to communicate with people on #threads of my choosing."
It is literally impossible for someone to take that choice away from you. Suppose Threads were to arrive in the Fediverse tomorrow. Worst case scenario: your admin defederates with them immediately and you have to migrate instances. You don't even have any pre-existing connections with them to lose. All your follows are ported. Stop fearmongering about this!
"I don't want somebody else deciding this for me."
