I emailed the EU (COMP-DMA@ec.europa.eu) explaining why I think #Google's new anti #sideload measures are problematic.
They responded stating they "welcome feedback from interested parties", noting that the #DMA does allow "strictly necessary and proportionate measures to ensure [3rd party apps/stores] do not endanger the [hardware or OS] or to [allow users to effectively protect security]".
May be worth sending an email explaining your opinion on the necessity and proportionality :)
