I don’t know about this, but only because Steam has a very unique position in their market. Lots of intense loyalists for Steam means long-term projects yield hype and reputation.

For example, the Steam Deck was a high cost high impact long-term project, and it wasn’t even in the interest of leading the handheld gaming market. It still brought them a lot of good press, and it also spearheaded the adoption of handheld gaming PCs - whether running SteamOS, Windows, or other linux distros - most of which are using Steam as the primary gaming library.
