Sorry but that reply is verging on the delusional and it's ironic, if not typical for social media, that you accuse me of ignorance. Linux vs Windows doesn't even matter. I'm a European who has been using Linux as a daily driver for the past 20 years and I know that the majority of popular Linux distros are mostly in US hands. Perhaps there was a misunderstanding and I wasn't clear enough about the scope of my comment. I meant it to apply to a situation in which the US is really no longer trustworthy and Europe needs some almost complete independence, not just about increasing digital sovereignty a little bit away from US products.

If there was a real conflict between the US and Europe, whether an open conflict or "cold war" type, you could be absolutely certain that every supply chain you're using is going to be mostly under US control. Open source is irrelevant for that issue, you're not compiling your own Linux distro and all software and your compiler toolchain and use your own repo hosting (and switch off all undocumented backdoors in your CPU's "management" engine). Funny enough, even if you did that, the hardware on which you run all this is almost certainly fully under US control. Guess where American Megatrends, Phoenix, AMD, Apple, Microsoft, Intel are located. The same for every phone operating system. Binary blobs nowadays either come from China or from the US and their chip manufacturers (e.g. in Taiwan).
