I associate this sort of disrespectful crapware auto-opt-in behavior with Windows, not macOS. Times are changing.
But I don't say that with any joy. I find the OS(es) to be getting buggier and buggier and I am saddened by that.
That certainly raises the bar.
The most notable one I saw was a recommendation to download the KFC widget on my iOS home screen. As someone who's never been to KFC, and never used either their website or app, this "suggestion" is indistinguishable from an ad.
Apparently this is triggered due to being "in close proximity" of a KFC (e.g.: due to walking through a mall).
You can disable these ads, but they're enabled by default.
