Hmm. In Chromium Edge, my new default browser, AFAIK the UO plugin will still work perfectly unlike in Chrome, meaning I rarely if ever see any ads.
The closest thing to an ad in VSCode or for that matter Terminal would be .. I guess hints at ease of Azure cloud services? Never found it intrusive myself, and I do AWS.
I was kind of trying to say I haven't seen any ads, just non-intrusive integration with other MS services, in response to the ads reply I got. Sorry that was actually rather vague and roundabout.
Mostly because Microsoft became more like Google in recent years. :P
