You ignored the 500k per year contribution to linux, VS code, the ongoing effort to fully open source dot net, them dumping Edge for chromium, their contributions to chromium especially on efficiency for battery is non trivial.

Microsoft could open source Windows and people will still mention EEE. Impossible right? But, open sourcing dot net was inconceivable just a few years ago.

You're talking about EEE. In fact, the organization that's actively performing the EEE strategy is Google. It's quite easy to spot if one isn't blinded by fandom.

E.g. webkit -> blink, rss, bundling of apps on android prevent manufacturers from using forked android, chrome OS has only one browser - MS didn't even do this to get in trouble, AMP project, and then experimenting with removing urls from the search page.

So whatever floats your boat.
