I'm doing a PhD in Berlin, living in Kreuzberg and I can tell you far from all of the programmers that I know want to live here!

What makes Kreuzberg attractive for startups and a Google campus is that it's central and perfectly connected infrastructurewise. Most other regions like Schöneberg, parts of Friedrichshain, Prenzlauer Berg and maybe Moabit, are all harder to reach from some other regions, even though more start-up employees live there. You can see on the maps of rental e-scooters like Coup how during the day there is a lot of activity towards Kreuzberg whereas after work the district is basically empty of their scooters. Imho kreuzberg is too dirty for most startupers. I guess they don't want to see the heroin junkies of Kotti when they do their grocery shopping.

In general I liked the sentiment of the activists against placing a Campus in Kreuzberg. Nevertheless I didn't like much of their public attitude ("bullets for google") and some arguments seemed superficial ("other Google campuses have increased rents" idk about the causality and factor here). I wouldve liked a Google campus in Schöneberg for example, just as I liked the Google campus in Madrid. In Madrid it offered a nice environment for work, some interesting talks and I didn't feel like it was in an artsy district that suddenly gentrified and turned hip. This could've added something to Berlin, but meddling with the activist scene in Kreuzberg was a poor choice.
