Yeah, just as free as his free offer to "... maintain CK and all the other stuff if you want".
You could argue with users heavily depending on CK (or ALSA hacks, or System V, or else) that they should not put themselves in such a position. If their software had been better designed they would not have been so dependent in the first place, they did the wrong thing, etc., etc.
You will probably be right. So much right that they will just switch back to an operating system that actually cares about support and backward compatibility. Even for "bad" users.
I do not blame Lennart for the great software he writes for free. I do not even blame him for how fast and how much software he buries. I was only blaming him for his extremely naive "just a free offer" above. No drug dealer is that naive.
