I think it's about company image. Microsoft has a long standing reputation for bundling crap and bloat its OS, while doing whatever-telemetry and harder to catch as the author of the OS itself. Valve and Steam has a much better reputation for now, and is respected by many players. I'm not saying it's perfect but at least it's loved by players whereas Microsoft/Windows is more into the hated category, for good well-deserved reasons.
