Not really. The PR has a description which Microsoft puts a one liner ad for something on the bottom of it. It does it when you use copilot to submit the PR so instead of the AI doing just what it's told it adds an ad.

I mean it's not major, easy to ignore but it feels a bit egregious because instead of it just being an ad on the page like "look at this feature which you have to upgrade to get" it's actually injecting it into the content part.

A lot of these request and code are at least partially reviewed or generated by AI. I think this article is talking about AI generating ads when writing the request, the review, and/or the code.

I doubt any of these ads are trickling down to product as long as the maintainer is mildly careful.
