We're talking about an open social platform which half the world's population uses, so it's effectively a public space and the fact that a simple political opinion could be enough to cancel my account means that when hundreds of dollars are on the line, my voice may be effectively silenced.

It's a huge problem and even if you don't realize it now, it is going to be a huge political issue in the future.

It's not that simple, and I hate it when it's inconsistent.

For example, even in the US, courts have established that Twitter is a public forum with respect to what politicians (such as Trump) say. But do other people get such protections?

In my country, Romania, the supreme court declared that Facebook is a public space, so if you say something like "the police can blow me" you'll get a letter from the police telling you so show up at the station so that they can fine you (swearing is illegal in Romania).

But Facebook can take down something I can say in public, meaning I'm not allowed free speech. It's not fair that I suffer all the consequences of a "public space", but none of the rights.

And at one time, the 1st amendment didn't even exist. Then, the argument was, "You don't even have freedom of speech, so don't bother". Just wait and see, eventually a case will reach the Supreme Court which will make us finally face facts that you can only blur the lines so much when dealing with private companies operating large-scale and general social platforms. After a certain point, it's a public forum and your rights should be equally protected if Facebook is to operate in your jurisdiction.
