Sorry, I forgot to directly answer the questions. - I think a platform doesn't have a specific responsibility to rebroadcast everything. If I don't like what things they choose to rebroadcast I'll find them less useful and start using a different service. - For content that I don't want to see, they should introduce any hurdle they want. I am only annoyed with censorship when they get in between the sender and the receiver without asking the receiver first. For example, censoring spam and porn is fine when done at the request of the user who would receive the spam and porn. Censoring misinformation is less fine because it has to be done without permission of the receiver. The receiver may be gullible and stupid, and then it looks like censoring misinformation is good. But sometimes the receiver is smart and better informed than the censors, and it's not easy to tell in advance. - Same as the previous, the categories for which it is OK to introduce friction are those categories that the user who would receives the messages asks you to censor. For example when an ad is irrelevant there is often a button you can press to tell the platform that you don't want to see those kinds of ads, and then they start showing different ads. I would like something similar for spam, porn and misinformation. - I don't know about competition, network effects seem very strong. Instead of having a special network only for special people who like free speech, I would prefer to change the wider culture so that the mainstream social networks support free speech. It's either that or wait for some crazy billionaire who happens to value free speech to buy the mainstream platform? Seems unreliable.
