I don't feel like the purpose of this movement is to punish FOSS software providers simply because they are based in the US.
Ente is a FOSS provider that does good work as far as I can tell. In my opinion, they should be supported and grouped together with the "good guys" category (as of today and right now, excluding any future bootlicking tweets their CEO may post).
There's an argument that this group is truly focused only one European alternatives, but I believe in the absence of one (and personally when there only bad/significantly-worse alternatives) some non-EU companies should be listed and supported.
