Had they followed through with that, it would be compulsion and the comparison to slavery would have been warranted. And the devs did exactly what I would have and what they should do, which is to withdraw any software they're not willing to support. To my mind this process is exactly what the OP was talking about: devs offer software for free with no support because that's what they're willing to do for free, someone demands more free labor from them under the guise of accountability, devs say "I'm not willing to do that and if that makes distributing this software illegal that's fine, we'll pull it down", lawmakers back down and move on to gazing in the mouths of other gift horses.
