For power users, you just need to wait for the 24 hour time frame.

Remember that this is just the beginning. The option will sooner or later be removed for good. I have no doubt about that. So sticking with them is wasting precious time for me.

I really don’t know how to move forward with this.

I already did the moment i heard of that. I was fed up with google anyway, but this was the proverbial nail. I have one dummy-phone with a fake-account for android-auto, and one phone with a fake-account for banking (sadly they ALL need an app and i need them all). My phone currently is google-free and the moment it dies, I'll get whatever non-google there is at this time then. If the camera of that one sucks, I'll get a DSLR, like back in the days. At home google is already blocked for years now. Including Microsoft and the other major US-american shitlords. Internet is a minefield of shit, but that's what it is. I've enjoyed the greatest time with the internet, and can be happy i was so privileged.

Google and Apple can bring 0-day fixes much faster

Might be true, but also totally irrelevant. As G+A are 99,99999% of target demographics of hacking/phishing/spamming. Not the 5 users globally with PostmarketOS or the other 3 folks with lineageos or whatnot. Noone cares about those.

wallets were actually easy to hack.

And here I am, still having my notebook from back when Bitcoin started :-) Yeah sure, i get you. But all arguments aside, it should simply be the user's choice. Live willingly in a totally protected golden garden if you want, but please give me the option to just unlock it and live with "all the risk". I'm >40yrs IT-freak now, I only ever had ONE virus-incident, and it was my own fault and it did not harm. Besides that I only managed to have an archive of virii that came by. This fearmongering is only really valid for clueless people who browser piracy, porn or click on every shit they find on social media. I don't even use any social-media :)

And, if we will talk about this further, I am curious, what superuser functionality is currently hindered right now with the developer verification thing that you really need to use?

I instantly stopped caring to be honest. They made their way clear, I'm gone. The same I said bye to Huawei back then when they wanted to MAIL THEM AND ASK for an unlock-key to your own expensive hardware. Never bothered them again. I have no other power in my control than to vote by wallet. Even if it's as insignificant as it is right now. At least I'm not part of it. Knowing what is wrong and still partaking in it, is embracing it. Goes for ethics, goes for "simple" things like this too. In my book at least.

Also, my personal problem with this is: No company will get my personal info for free. And I surely won't pay google to have it just so I'm allowed to install my own apps on my own damn phone. Would you accept this on your PC? Even Crapple lets you install apps freely on their MACs.
