But Apple hasn't been fined in the same way. So apparently if Google had kept Android proprietary, and made their own hardware, they'd be totally OK, even though there'd only be two phone makers left in the world instead of dozens like there is now?
I'm sorry but this move is garbage. I am British and I'm so glad the UK is leaving this horrible, success hating farce of a union. Google paid billions to develop Android and then gave it away for free under the Apache license specifically to encourage competition and diversity in the smartphone market. They then added a carrot of some apps and the app store if OEMs agreed not to introduce backwards incompatibilities, to avoid the J2ME problem of a hopelessly forked and buggy platform.
If they hadn't done these things, very likely Apple would have wiped out every competitor in existence.
The EU is sending a powerful message with this move: keep everything proprietary, pick a high enough price point to price out most poor European countries, and you'll be fine. Build an open ecosystem where competitors target every price point and you'll suddenly find yourself being an involuntary contributing member to the EU's budget. What a great disincentive to build products for the Spanish or German markets.
