> how these two things are comparable

Apple has done other unprecedented things, after claiming "if this doesn't change, we will take something from customers"

Apple rarely takes something from customers, to the point I'm searching for examples beyond iCards... which are back recently as Invites

“If DMA doesn’t change, we’ll drop some 25% of our revenue” sounds orders of magnitude bigger than “we’ll disable ADP”, which was the example given by OP.

It’s like a comparison of “I’d be mildly annoyed” vs. “I’ll burn myself alive” as far as reactions go.
