Should Apple be responsible for righting the wrongs of legislation in every country it operates in? I don’t think so. Ideally it would mettle as little as possible, even though they clearly don’t (see right to repair).

Hmm. I don't think the point is that Apple has to "fight". The point is that Apple needs a moral high ground and is willing to completely give up the UK market (which I understand but don't necessarily agree with). I don't see that happening with today's environment, considering that shareholders will happily fire Cook over that.
