Am I the only believing it should be a free market, where each company follows the strategy it prefers? Let the market decide if repairability is desired or not. If customers really want it, certainly there will be companies offering it. Much better to have millions voting with their money and purchases than a few bureaucrats deciding how they believe things should be.
One by one, remove the replaceable battery, remove the 3.5mm, remove the microSD card slot (and neuter it software side so it's near useless), some will complain, but the majority will just adapt to it, buying new phones more often, wireless earbuds, more expensive phones with more storage. Just as the companies wanted.
Looking back, the majority will see all the things they lost but by then it's too late (or not, change can happen thanks to movements like RTR).
So, the free market works more like tyranny of the majority in practice.
