It had been in the works for a while, but now it has formally been adopted. From the article:
The regulation provides that by 2027 portable batteries incorporated into appliances should be removable and replaceable by the end-user, leaving sufficient time for operators to adapt the design of their products to this requirement.
Why not force Apple too?

Because besides Android and iOS, there is also for example Tizen and KaiOS. Is there a market for custom software for those devices? And if not, why require it?
