Well I don't use this extension, no do I plan to. That aside, anyone can fork this repo and maintain it themselves. It feels like a stretch to say this isn't a benefit to society when anyone can use it and fork it without limitations or payment.

The rest of what you're saying is inapplicable here, but is applicable to other stuff they do. EEE is usually when they buy a product or service (Skype, for example) and kill it off (which was possible because Skype was a closed source service). You can't really EEE an open source project. Even vscode has popular forks, and there's nothing MS can do to stop them (outside frivilous lawsuits I guess).
