If you look at the current things the EU has forced them to open up (app distribution and NFC payments), both of them are things that Apple was already actively monetizing.
To compare this to a non-monetized accessibility feature is a bit disingenuous.
The whole notion of ‘fairness’ is that gatekeepers should allow others to compete on even footing. That can be fulfilled by granting EITHER everybody OR nobody access to the market (but not: only yourself).
