What they want is to get rid of apps like YouTube Vanced that are making them lose money (and other Play Store apps)
what about us losing control over our own devices? do you like losing control over devices you paid for?
You are inadvertently reaching the true core of the question. The ones who have "control" over a device, are those who control the software running on it. Be it the bad guys (in the case of a malware-infested device), a giant corporation (in the case of a locked-down device), or yourself (when you can install and replace any software you want on the device).
