yeah, the big Social Media giants censor where they can. Until last year it was certain critical videos and channels like for example the one of Styxhexenhammer666, that got completely blocked and you got this when accessing his channel (I'm not sure if he has "criminal" opinions, he just seems to be "dangerous"):

And since about half a year before the federal elections last year, the censorship became more extreme and is ran by establishment/leftwing organizations who allegedly censor with a political bias and suppress content from going viral (lot's of users confirm that impression) after Merkel did stuff to Zuckerberg et al:

And since about half a year, Germany has an extremely restrictive and hazardous law where you can get fined with millions as Social Media provider if you don't delete illegal content. The law is highly controversial and quite likely illegal.

So, yeah, we need proxies to access not just non-left information and sometimes even left leaning information that has the wrong impetus.

Bottom line: Under Merkel, Germany (and the entire EU) became authoritarian in the past ~half decade. Don't let yourself fool by the propaganda.
