Remind me who was president in 2020..

Fair, that one wasn't a good example for this.

Though IMHO it's not just a Biden problem, it's a "everybody in power" problem. They just can't seem to resist (ab)using their power to shape the conversation and censor their opponents. It's also not new, it's been happening for hundreds of years at least. But it did get a lot more brazen under Biden IMHO with Twitter/Facebook etc and admin officials telling private companies what to censor (err, "moderate").
