Hatespeech. Criticise religion? Hatespeech. It would of course never hold up in court, but that doesn't matter, for social media platforms deleting anything that could be construed as hate by anyone who feels offended is the path of least resistance.
You are not made accountable for breaking laws that already existed, you are being censored for something that is not illegal, never was, still isn't, but could offend someone if it's disagreement on a sensitive topic. It's the end of any sort of free speech on social media in Germany.
