Can you run common apps from the play store if you choose?

I think you can install Google Services (including Play Store) if you want, but there are alternative like Aurora Store that lets you download apps from Play Store without Google Services, but obviously you can't buy apps from it
the main concern is probably banking apps or some apps that require Google Play Services to run
probably will take a bit longer because it will happen in certain countries like Indonesia and Brazil first (i.e. not EU countries)--basically the countries with rampant
apkscamming, unfortunately. I think this move is also partially forced by the government in those countries, but that's just my conspiracy hat talking, note that I'm also against this move and much prefer a scam education (I'm in Indonesia).
