They pulled a Red Hat 

 this is why i publish as CC0 or Unlicense.

easy to smack that shit down when it's public domain.

but reading through both of those licenses makes it clear that the governments and the corporations that own them reserve the right to change any rule they like no matter what is already written down and widely distributed.

i only put licenses on my shit because i am virtue signalling my rejection of copyright. otherwise i'd put nothing on there. but probably if i put nothing on there they grandfather it in to some adhesive contract imputed by the host, ie github.

this is also why the sooner we can get software repository hosting off the silos the better.

the denial of availability attack is the most dangerous one. 

 You can always change the license moving forward but doesn't affect course already released under MPL.
