A group of over 40 European organisations have recently released a statement calling for the EU to set up a European Public Digital Infrastructure Fund.
They call for this fund to support Digital Public Spaces, that are, among other things, based in FOSS, and ensure privacy by design. The statement gives three examples: #Mastodon, #PeerTube and #ActivityPub, stating that they would benefit from such a fund to further flourish.

The @EU_Commission has been supporting the fediverse for a while via @EC_NGI. This picture gives an idea of all the projects that have gotten funding via NGI.
