The claim that government wasn't involved in these cancel campaigns has been shattered. The Obama administration pioneered the efforts with Operation Chokepoint, which basically tried to get banks and the financial industry to "voluntarily" (under threat by their regulatory agencies) deny service to the gun industry. Now that's been expanded to deny access to social media and any speech or financial platform for, basically, everyone the left doesn't liked on whatever thinly veiled excuse they can come up with. If you're a CEO or a high level corporate officer, better not speak out or you will be hounded out of your job, or have your bank cancel your accounts, or whatever else they can come up with. And in many cases, there's a hidden hand of government applying pressure behind the scenes.
That should violate the 1st Amendment, but if it's kept secret, how would you ever know?
