I find this disturbing.
Also, although extremely unlikely, I would imagine Github finally panicking upon a large exodus of high-profile FOSS projects.
Most companies are allergic to lawyers. As in, they'd rather avoid the issue outright and go elsewhere if a hint of a legal question comes up. The fact that they didn't bother floating this change by the greater community at large does not give me the warm fuzzies that they learned their lesson.
But then, they took a week to look at the reviews (ostensibly; I, as well as others, never got any response to them), went and made some minor changes (which were not enough to address the problems at all) AND BROUGHT THE CHANGED DOCUMENT INTO PRODUCTION RIGHT ON THE NEXT DAY, without any further review or warning. That’s like bad.
