Logitech are my go-to example of a company that does the right thing and deserves recognition for it. They kept their squeezebox.com servers going for a decade after they discontinued their Squeezebox hardware audio players. At the same time, they funded a maintainer to keep improving the open source server software that users can self-host on multiple platforms (Linux, Windows, macOS, Raspberry Pi). Two years ago, they finally shut down the squeezebox.com servers that they were running but the server software is still being actively maintained: https://lyrion.org/

I recall there is also an open source and hardware speaker but not 100% sure it's from Logitech.
