I don't expect them to do that, much too easy to get slapped down on by the EU. I do expect that non-Apple/MFI chargers are USB 2.0, and I do expect are limited to slow charging and might come with a nasty-gram in the OS when using one. I lean against the nasty-gram as you can use some shit-ass lightning cables and iOS doesn't generally care, but the other two I would say are near certain. What will be real fucky is if they don't have a faster data transfer speed at all.
