There does seem to be momentum now for the EU to start building it's own infrastructures, from cloud services, AI services, Defense, and many other areas. I think that momentum will gather further pace, as more companies start to find ways to reduce the impact of US policies. The current trade war is one example of how vulnerable we are, this seems to have distracted trump from Greenland and Ukraine / Russia (I guess he can't cope with more than one project at the same time).
So what can people do to help promote all this, Matrix is starting to gain ground, I would like to see conversations open up in those forums that last beyond a few words being exchanged. To some extend the Fediverse is also gaining enough groud to start to worry big tech.
One of our strenghts is we have the ability to collaborate, to what extent can be truly move away from the USA, and do we need to, I guess due to the nature of Fedi, individually owned instances are safe, but what about where they are hosted and to what extend would those hosting companies have to comply with federal orders (or is this getting too complex?)
