All factory operating systems come with ads and bloat and spyware, Apple/Samsung included. Google remains the lesser of all other evils because at least to date, they offer an open source OS, bootloader unlocking, and root. A community driven mobile OS is absolutely where we should go, but for now and the foreseeable future you can call a Lyft, deposit a check (in America), and do other mainstream tasks on AOSP flavors without Google/Apple/Samsung having to know anything about it. It's never been easier to make the user friendly choice too: https://grapheneos.org/install/web

It's not like buying from Samsung is any better.

for some reason i read that in archer(animated) voice.

Probably because it's a dumb useless comment in the same vein as most of that show.

I read this in a whiny high pitched voice with my nose and lower lip pulled up.

Don't recall my old nexus devices having ads in the OS. Disappointing where Google has taken this.

Technically they already did a built in ad with Android KitKat. Mostly benign, but I do remember being at an Android event and KitKats samples being given out to everyone. As well as KitKat wrappers being branded with the Android logo for a while.
