Interesting. https://free-software-logo.codeberg.page/ by @mray@social.tchncs.de suggests a logo for Free Software. It’s licensed as CC0 (No copyright) for free use. This can be used to indicate #FOSS / #FLOSS instead of using a company logo like e.g. from GitHub Inc., that may be used to _host_ free or open software but has a distinct logo of it’s own (the Octocat logo is a registered trademark).

It reminds me a lof of the Open Share and Open Source icon e.g. of the OpenWeb Icons set https://pfefferle.dev/openwebicons/ by @pfefferle@mastodon.social and may even be a nice addition.
