Terrorism is the excuse they normally use yes, it's very easy to call anyone they don't like a terrorist and then do anything against them. Look at Autistici/Inventati, it wasn't safe in Italy, and just this week, Dutch police under orders from the US have seized one of their remaining physical servers.

Copyright infringement is the other big excuse. People like Louis Rossmann get their journalism taken down because they showed 3 seconds of something relevant to the story.
