No where does that source say Biden tried to shut down the Internet. The closest is this part

Donald Trump publicly advocated that “in some places” we have to talk about “closing up the Internet.” He got his wish, but it came after him personally following his election in 2016. The very free speech about which he made fun turned out to be rather important to him and his cause.

Also I can’t take a site seriously when one of their sources they link to is the Twitter user “End Wokeness”

There are some parts I agree with, but there’s plenty there that’s right wing dog whistles for “I want to say hateful things and have no consequences” free speech
