I suspect that making exceptions to their "30% of all digital services" rule opens them up to lawsuits of favouring one company over another, not being a level playing field, etc. Since they are in a near-monopoly position, claims of an uneven playing field might trigger really bad judgements against them (ie. 'Apple must split their hardware/software businesses', or 'Apple's hardware arm may not deal in mobile apps')
