They're also co-founders of the Rust Foundation[1], the major member of the select group of companies at the table at WHATWG[2] (which amongst other things decide on the future of web technologies, including JavaScript) due to their browser's market share, and a "visionary sponsor" of the Python Foundation[3].
They also develop a few programming languages themselves, like Go and Dart (not to mention their polemic Java implementation), besides their own OS (Android, Fuchsia).
A company as large as Google is kind of expected to be using every technology in existence, but I still find it interesting how they're also making sure they also play a major role in the evoluation of such technologies by being part of any Foundation that might have any relevance whatsoever (if not via their own languages, at least by exerting influence on everything).
