"but they are under no obligation to make sure it reaches other people's feed.." Nice euphemism for censorship. Social media is common people writing and reading. And they choose which people to follow etc. "stopping a post to go viral" means in this context activily manipulating and interfering what information does and does not reach other people. That is something very different than a newspaper refusing to publish a certain article.
