I actively support the work of/at CCC and Wikimedia DE. And I run a non-profit computer museum.
I put demands on my readers: You are required to detect irony. But, spoiler alert, each of the following startups has a valid core of truth. Can you find it?
I'm on the web since 2000 and I had many generations of websites, some (most) of them being down nowadays. Sven.Köppel.org was my website in the 2010s. Ufopixel.de is another old project I was involved in. There are still plenty of ressources which can be found at my old website at Goethe University.
There are a couple of other Sven Köppel around, which are not me. These are for instance @testpilot76, this instagrammer or that person in Hamburg.
