I really don’t understand the people who rush to defend Meta/Facebook on bill C-18.
Because it is what is most likely to provoke a reaction? Like all internet comments, the words aren't grounded in anything. They are crafted such that they attempt to get something back in return (a reply, a vote, etc.) If you want to learn what people really think, you need to find a way into their private journal (without them knowing, else you will influence the activity). As soon as other people become involved, the motivations change.
(on an open source social media platform of all places!)
Well, if Lemmy ever becomes popular, it too will become subject to the same law. Open source especially doesn't like such encumberments. This surprises you, why?
