The owner of X appears to me a threat to democracy and decency. Now he supports the extreme right in Germany. I find this unacceptable. You can find me on Bluesky (@martin-peitz.bsky.social) and LinkedIn.

Switching back and forth between being a lobbyist and a politician should be incompatible with "European values". It corrupts politics.

We are talking about undisclosed conflicts of academics. What about politicians? Here's Aura Salla, newly elected MEP, asking "not to politicise the DSA" - meaning little regulation. She was employed by Facebook until 2023, and described as "Zuckerberg’s woman in Brussels".
