It's specifically the US government that's guaranteeing a right to free speech and protecting freedom of expression. This is also a uniquely American thing, many other countries have significant restrictions on free speech. Free speech can be interpreted many ways, but one of those is to curate your platform and decide which messages you want to promote, and which you don't want to. YouTube is not an arm of the government so it's free to do whatever it wants so long as their actions are not discriminatory as defined by law. You're also free to complain about it.
