My angle would be that it takes away digital freedom and drives us (#Europe) even deeper into the technological dependency from the US.
For example, #RyanAir now forces its customers to install their app, which (of course) is full of trackers, needs permissions to access your Advertisement ID, etc., and generally needs unwanted and intrusive permissions.
I know @digitalcourage have a campaign for declaring the right to live offline as a human right. I wouldn't go that far, but they have a point.
But back to the topic: If #Google/ #Alphabet locks down #Android, they convert it into a *closed* ecosystem, taking away further digital freedom from EU citizens. They want to put in place additional barriers for people to publish their own apps like
* having to reveal your real name
* *paying* to Google for the right to publish on Play Store.
It should be obvious that's not exactly
* creating opportunities for innovation. (In some cases the open source copies of Apps are better than the original ones.)
* creating/maintaining an open/liberal market.
