If that doesn't summarize everything that's wrong with this fucking monopolist, that controls YOUR device that you paid with YOUR money but ultimately isn't yours to do as you please, I don't know what does.
The only thing that makes Google a bit tolerable in the mobile space is Apple, because Apple is even worse. At least you can (still) sideload stuff in Android - although Google is about to make that impossible very soon too.
What if you don't want a Pixel? Or a Fairphone? Or one of the very, VERY few cellphones that you can install a deGoogled OS on?
There are precious few ways of escaping the Google monopoly. I own a Fairphone running CalyxOS, and it happens to be the phone I want because of its excellent repairability. So lucky me. But if I didn't want a Fairphone, nor any Samsung phone, nor any Chinese cellphone, and certainly not a fucking Google phone - because I'd rather cut off my left nut than give Google money to escape Google's surveillance, that's just too rich for me - then I'd be SOL.
My point is, if you refuse to be Google's bitch, Google backs you into a corner. Just because you're happy with the corner doesn't mean you're not stuck in a corner.
All right then, name a single plug and Play solution that allows you to dismiss a notification on one Android device, and automatically dismiss it on another without any intervention.
Systems and macros such as Tasker do not count.
No seriously if there were any alternatives I would love to know about them
