This piece is pretty slanted. I'd recommend some counterbalancing coverage from, say, Mick Masnick (who is unabashedly a big tech booster): https://www.techdirt.com/2020/06/23/hello-youve-been-referred-here-because-youre-wrong-about-section-230-communications-decency-act/
The situation around 230 is complicated. Does it protect X and Tiktok and give them an out for failing to police dangerous stuff on their platforms? Absolutely!
But without it there'd also be no Mastodon as every admin could become legally liable for the speech of the users on their instance.
So. Yeah. Messy.
