For example `sudo apt update && sudo apt upgrade` CLI log now includes an ad

Yeah. There's a lot of silliness I'll forgive, but adding ads into cli utils was the "Ubuntu has jumped the shark" moment for me.

Now they've stepped onto this slippery slope, I don't intend to be on the ride with them on the way down.

I didn't touch ubuntu for a while (just have to support it for some work stuff) and damn the more I hear the worse it gets... wtf

No they don’t, packages can do whatever they want on install and uninstall.

You install a package called firefox that on install installs the snap and on uninstall removes it.
