I doubt Sony will re-enable anything. Chances are they could simply pull the PS3 from market. People own the hardware but not the IP. The idea that you can assert ownership just because your allowed to use it is something that doesn't fly in many other market segments, I am not sure why people think that Software must reside in a realm of its own.

Sony is not going after the people "installing" the hack. Just those distributing a modified version of their code. As a user you are free to hack the console, all you have to do is accept what goes along with it after you violate TOS/EULA/Warranty, which is normally a loss of service and support for the regular functions of the PS3.

I just said it. You COULD have put betamax into betacams and they would work. For reliability purposes sony advised against this and obviously ti no longer held true after many betacam revisions. Beta and VHS were not compatable but believe it or not HD-DVD and Blu ray are. The difference is in the discs themselves . In those combo drives did you think that they had two different lasers? The smaller numerical aperature had no issues reading the HD-DVD disks. Again you say they are just "different" but I have repeatedly pointed out to you that specificaly betamax and betacam were interchangable.
