I can empathize with not wanting to be involved with this anymore, which is fair enough, your choice, but there are solutions to the mentioned problems.

There are social or technical solutions to the problem of "too much free speech".

There can be decentralised filters set up that can be moderated by communities like democracy. You can have curators of content that can guarantee to bring safe and healthy content to you. You can have decentralised reputation, authority and reward systems for the content creators and the validators. And so on.
