It depends on what your goal is. I used to share your opinion, but find myself increasingly of the opinion that these ideals must be kept separate. Much as I like the idea of open source, not all open source applications or crowd-sourced data can keep up with companies with hundreds or thousands of people actually responsible for it. Similarly, when it comes to innovation, large resources and private investments are needed. If we focus too much on requiring every single thing related to software being open source, we risk the entire effort failing before taking off.

Open source is great, and if you care especially much about this topic that’s also great, but it’s still quite niche (the general public won’t care), while geopolitical sovereignty is a big topic many are rapidly coming to appreciate. Let’s start with this part where there’s already substantial agreement within the population instead of necessarily packaging them together. Switching over from sending our money to the US for the privilege of dependence to investing our money into our own companies seems a relatively easy and well supported first step, over European and open source and non-addictive and no obnoxious ads and low energy consumption and and and. All all worthwhile causes, but insisting on all at once is doomed to fail. IMO it’s better to move in steps, and start with the low-hanging fruit.
