You know these rules were drafted in cooperation with the EU right? Vestager was at Apple's HQ 2 weeks ago, and the EU spends millions to keep a regulator presence in Silicon Valley.
The commission knows they really don't have much to stand on, if they go any farther they know other EU countries are going to step in again (these rules are not very popular anymore after GDPR and now that the EU is falling even farther behind the USA economically).
The EU commission is a lot less powerful than a lot of terminally online Americans like to believe. EU courts constantly rule against them for overstepping their bounds and they have been caught submitting fake evidence before (see: Qualcomm case)
