> It's hard to imagine that any sane person who is just looking to use a popular editor would read some broad limitation of liability language like the above, and interpret it to mean, "By the way, we intend to quietly delete certain files created by a competing fork of this project whenever we find them."

Forks of projects trodding all over each others files is one of the more common problems that has happened, historically. Prior to the major efforts around freedesktop.org around configuration standardization, it was quite common. It'd be one of the first things I looked for when switching to a fork.

I’m not saying it doesn’t happen. I’m saying it shouldn’t be defended as good. It’s a defect. And in this particular incarnation it’s a defect that directly clashes with fundamental Free Software principles such as personal digital sovereignty.

I also suspect that few people actually believe it’s ok and these legalistic defenses are more about circling the wagons. How many people would defend Microsoft if a new Office version automatically and quietly stripped edit history from documents that were originally created by other versions? Would we be hunting for limited liability clauses in their EULA to defend the design decision?
