The way things are going it becomes a national security issue where those PR are coming from.
And TBH IMO such projects should be avoided in the first place regardless of what US is doing because they tend to use FLOSS as a marketing method than for practical development. Choosing projects which have multiple shareholders, so to speak, is much healthier in the long term.
I think recently it has been made obvious by the US that relying on US technology is a risk, because it can be used to bully entire countries.
So I think there is a movement right now of "non-US alternatives", but of course if you are in the EU and got burned by relying too much on the US, maybe it is wise to try to fix that by having some kind of digital sovereignty in the EU.
But I'm pretty sure many companies would switch to a Canada-based product if it allowed them to reduce their dependency on the US.
Some projects, especially high profile ones, do have US companies behind them (e.g. Google, etc) so you could claim they are US-centric, but at this point it becomes a question of why you are looking for an EU alternative. If it is to help EU businesses (like others mentioned), then unless you financially support these US companies (either directly or indirectly via, e.g., your data) it doesn't matter if the FLOSS project you are using is made by them or not.
