It’s not about the explosive growth (or not) of iMessage. It’s a matter of fact about the legal foothold that Apple now holds. That won’t be dislodged anytime soon. Whether or not Apple can get any market growth moving forward, now the EU will have to re-file any efforts to this ruling to them in the future should they try. That is a big deal. And nothing anyone in trying in the EU will move forward anything near the weight this attempt did.
