Apple says EU push for universal phone charger would 'stifle innovation' (engadget.com)

I think the specs could benefit from some "minimum-requirements standard" but the plug hardware should be off limits.

And Apple is right, every attempt to enforce unification is a hit to innovation, it's logical.

Without forcing an unified charger, the same aim could be achieved by banning manufacturers from bundling changers with all products, and by forcing them in include an adapter to USB-C with products that use another connector.

People would buy a charger only when they actually needed one, it could be a generic USB-C one, and manufacturers would have an incentive to use USB-C unless they could really sell the extra value of a different connector.
