Who actually edited the EBOOT at ps3news? Was it Team M33, or was it ps3news? That's confusing me.
At any rate, you spend time building trust in your product with a community (whether it's free or not). One stupid, childish thing like this damages or even destroys that trust. If this was done intentionally (and I guess that's still to be determined), whoever did it is actually, deliberately costing people money. It's one thing to do it accidentally; deliberate intentions to destroy your hardware drops the perpetrators to the bottom of the food chain in my book.
As for the "license" on M33-3, I suppose Team M33 can do what they like, but imposing your personal morality on your users is just immature. What they may be attempting to achieve in this case in the name of "antipiracy" is, to me, equivalent to requiring me to be of a certain religion, or to love and embrace seatbelt laws, just to use their cfw.
Something that's possible, I suppose, is that ps3news deliberately altered the M33-3 release to cause this kind of chaos, to intentionally discredit Team M33 (anybody remember the cyanide-laced aspirin on store shelves in the 1980's?). I don't know what the relationship is between the two, but it doesn't sound amiable.
