Could they? You'll note that the source article does not describe even a single example of Copilot, the product the discord server was dedicated to, producing slop.

At one time, Microsoft produced some very high quality software. Excel was an absolutely amazing product in the '90s. That quality has been on a steady decline, and that decline has quickened since Microsoft started investing heavily in OpenAI. Github once had pretty good uptime, now it forces AI features on us and is down a couple of times a month. Windows is full of in-your-face advertising and dedicated AI buttons. These features are not what people want, and don't help anyone. Thus; MicroSlop.
