There's no need to define it as hate speech, since the DSA purposely mentions a very vague "harmful speech/content" (not "hateful") which can in turn applied to whatever the EU sees fits.

For example, any objection to the current policies w.r.t the Russian invasion of Ukraine can be censored due to the DSA and this has happened recently to a prominent Italian YouTube influencer (Andrea Lombardi). His tweets were censored for his opinions about the Ukraine war.

How many other tweets are being removed which we don't know of because they are not coming from famous people who have channels to make themselves heard anyway?

For example, EU countries have used such laws to ban criticism of their COVID policies.
