How CAN google react on it? They might not like it a lot, but hey, they claim Android is open, so they can't do much about it anyway. They might try to exempt these devices from using google play store (man, that name is stupid), but they'd only shoot them selfs in the foot by doing so. The only thing (?) are the google apps like google maps and gmail. These are not free (as in speech, and neither as in beer). Not that I care, I avoid Google like the plague.

Besides, in European law interoperability has a special status IIRC.
