Louis Rossmann’s video is a good take on this. Basically the anti-repair stance they have held for so long is evolving into a passive approach where it is either too costly or too difficult to repair
What they are saying is that Apple is now fine with people repairing their own devices because the cost of the equipment/parts to replace parts in their own devices likely is more expensive than the average Joe is willing to sink into a DIY project, with none guaranteed results, as opposed to just send it to Apple for a repair.
Sure people can now send it to a third party for a fix but if the cost for a repair at a third party shop is marginally lower than an Apple repair, Apple is betting that a customer will likely choose them vs. a third party.
Apple will be gatekeepers over NEW replacement parts for their devices so it’s a win win win for them. They win if you buy their parts to replace parts, they win if you take it to a third party and you buy their parts and they win if you take it to Apple for service and repairs.
