USB is superior to lightning, no question about it, but this legislation strikes me as very odd. Do they legislate that all lamps us the same type of lightbulb? Is there a fine for incorrect sliced bread thickness? Do all doors have the same handle and mechanism? I understand things like fuel nozzle standards because there is a consumer safety concern, but mandates like this seem strange even if technically advantageous.
GOV takes notice when single companies are dominating a space and pushing proprietary things for self-serving profit motivations. See many stories of monopoly or nearing monopoly entities flexing their dominance for self-serving motivations and GOV stepping in to deal with them (because no one else had enough power to do so). In this way, GOV is last resort.
You don't see this with lamp makers, car makers, bread makers, etc because there is robust competition in most manufacturing with no one lamp maker heavily dominating the space. Let a lamp maker come to dominate the space with a proprietary lamp socket that requires consumers to either pay up MORE for bulbs only from that entity or for other light bulb makers to pay a license fee to use the socket and GOV will likely have to step in to standardize light sockets too.
Basically, if growing, dominating companies don't get too greedy & self serving, GOV stays out of their hair. When companies start looking like they might be able to soon own the bulk of a market and are making moves that exploit that dominance, GOV often moves to take action to re-level a playing field in matters like this.
If you look back at history, you see this over and over. Generally consumers benefit when GOV pinches off the corporate exploitation of consumers through proprietary things that benefit a single entity.
"We" Apple people will gripe about this only until Apple either complies or goes wireless. We don't gripe that there is no Lightning in the other products where Apple is already USB-C. We don't call Apple out as wrong for voluntarily embracing USB-C in those other products (no GOV mandate required). It's only in this
ONE product line where Apple still clings to Lightning that we "love" Lightning. As soon as Apple turns this page, we'll see Lightning like we see the 30-pin... or firewire 800, etc.
Until then, what Apple has for sale right now is absolutely right... and everything else is wrong. When Apple changes that, "we" change right with them... as if we never felt so passionately about the old option at all.
