i don’t see that. i see carmac reminiscing as, wouldn’t it have been nice if this had happened rather than that, while clearly acknowledging that his business partners would not have gone along with ‘that’. the implication I draw, having no more info than these tweets, is that, after some discussion, JC and Id compromised on using the GPL to license the DOOM source, versus not releasing the DOOM source. The GPL allowed wide general availability of the DOOM source, which Carmac wanted, while being acceptable to Id’s business needs as Id saw them at that time.
