Christ, this is such a stupid take. You'd think that someone who was around on the fediverse would have an inkling about just how many instances are based in the EU and Germany in particular.
Just because a country or userbase wants a degree of moderation and accountability, and doesn't tolerate hate speech, doesn't mean that views are censored. Basic Popperism stuff right there.
"No, you have free speech as well, but it is also has its limits."
Which is true. A lot of Europe learnt from World War II that certain types of speech should not be tolerated. In the rest of the article there are examples given - neo-Nazis for one. I am not particularly keen on tolerating the freedom of speech of Nazis or others that call for genocide and killing.
