@hannes2peer for my part, I'm personally ok with the FAQ being removed, for the specific reason: 1) it's rather outdated anyway and deals with no-longer supported features like private groups and hidden accounts, 2) many parts go into too much detail or describe rather obvious things..

So the faq could IMO be removed/replaced with some other faq. However I also agree with your opinion: It can't be right if a contributor to a collaborative GPL-like work can ask to remove all their contributions any time later. This would be like Evan Prodromou or a Linux kernel developer asking to remove all their code lines from a work, 2 years later, after others have continued the work. @simsa0
