I work for Microsoft/Azure and my incentives are (roughly in descending order): minimize large/long outages, ship lots of stuff (with some concern for customer utility, but not too much), don't get yelled at for missing mandated work (security, compliance, etc.) I'd love to improve product quality, but incentives for that are negative. We're running a tight ship, and every second I spend on quality is a second I don't spend on the priorities above. Since there isn't any slack in the system, that means my performance assessment will drop, which I obviously don't want. Multiply that by 200k employees, and you get the current state of quality across the whole product portfolio.

My experience in the Teams org is the same. It's all about security, compliance, and recently AI. Fixing bugs and similar "non-flashy" work is a sure way of postponing one's promotion indefinitely.
