I dont see the problem right now:
If Jens keeps his word, it seems a good outcome.
Every hardware/software developer gets the free DDK and users get a bugfixed and improved and supported P96 that will of course cost some bucks. Furthermore the old (current) Aminet archive wont be removed, so Amiga users that dont want to pay, are not compelled to.
This reminds me of how the free CGXv3 was released and afterwards v4 was sold comercially with a fair degree of success because it had many interesting new features that caught former users.
