It only ever was present because Sony wanted to cheat EU import tariffs - by allowing other operating systems, it could be imported under the lower general-purpose computer rate.

IMHO, removal of this feature should have triggered Sony having to pay back the amount of taxes cheated.

I recall they lost a bit on selling the consoles to the USAF that were used as computer cluster. (The consoles afaik sell/sold? at below cost and rely on games to make up the extra cash) So they lose money on consoles that aren't having games bought.
