This has come to a head as plarforms have grown larger. Note that even if some platforms were strictly neutral, they'd still be affected by the changes the government is proposing. It would have been very unlikely that none of the major platforms would have moderated beyond legal minimums.

seems like a lot of lawsuts and not a lot of legislating, from the wiki.
Why would companies find that preferable to moderating themselves? If the government makes laws prohibiting that stuff, then that means the companies could get in trouble if they let any of that through. If companies self-moderate, then there will be less pressure for laws like that to exist, and the companies won't get hit with penalties for missing a few things here and there.
But, as graeme has pointed out, this idea of any moderation increasing a platform's liability is as wrong as it is widespread.
they'd have a regulatory shield and probably retain carrier status, rather than sticking their necks out by selectively moderating content.
a moderate amount of moderation is my preference, but i see the value in freer speech zones on the internet (that i can mostly ignore).
