Question is for how long. Time to slam the hammer on them.
Unless it is some kind of anti-competitive behavior like they intentionally stiffening adoption of standard competing with their proprietary patent-encumbered implementation that they expect to collect royalties for (doesn't seem to be the case), then I don't see the problem.
That hammer is very close to going away; if the EU does force Apple to really open the browsers on the iPhone, everything will be Chrome as far as the eye can see in short order. And then we fully enter the chromE6 phase.
