They didn’t protest against the new Spandau Siemens campus either. Siemens being in the arms industry, while Googlers openly protested against any military-related research during the same year. It’s just that no nobody wants to live in Spandau.
The area around BER is even further away, and the close-by Adlershof is pretty much Berlins center for STEM research (many suppliers are there too). Could be a good move.
