No, they have to keep with laws of the countries they operate in. In difference to the US: - some countries clearly differentiate between private and cooperate - have proper free speech laws which are not limited to government inference into free speech but free speech itself - have laws about discrimination and protection of political organizations which does not allow you to arbitrary "block" people etc. I don't know about UK law. But I'm pretty sure this would have been unlawful in Germany, and potentially all of EU (due to EU wide regulation, but while I'm pretty sure about Germany I'm less so about EU wide regulations).
