Not the commenter but macOS regularly spams people with:

- Ads to try Apple Music free for a month.

- Ads to try News+

- Ads to try Fitness+

- Try Safari (if it’s not your default browser)

- Try/log into iCloud if you’re not logged into iCloud.

- Try the latest macOS release if you aren’t on it.

As an aside, you do not want to even log into the Mac App Store with a personal account on a work computer.

Logging into just the Mac App Store effectively logs you into your iCloud on that machine and sensitive personal data is then strewn across various files under ~/Library. The iCloud sysprefs will claim you are not logged into iCloud but ~/Library will show you the truth.

I am a macOS user and have never seen a popup or ads for News+, fitness+ or Apple Music.

In addition to that, what personal data are you talking about in your last paragraph?
