No, I am not. That is the stance of the EU. Switching is a matter of European security.
What "people" want is already irrelevant and whether the GUI is consistent or not couldn't matter less.

This! Software is stuck in some illusory ideal from the dotcom days, a global market of meritous choice. It's long been political and about sovereignty, control and security. Some comments above sing the praises of Adobe as a "no alternative" software. So, remember that time when Trump passed an executive order banning Adobe in South American countries [0]?
The US does not get to use access to tech as a weapon, so they're not good enough by wider criteria in a changing political world. It doesn't matter how good are products by Google, Microsoft, Apple, Adobe, Meta...
I also happen to think they're technically inferior to a diverse inter-compatible and free ecosystem, but that's becoming a side show.
In a way its good that there are no European vendors. The coming change cannot be mistaken for trade preference. People are being "forced to be free" of dangerous influence [1].
Oh well, that was a misunderstanding. If people are forced to use a new OS whether they want it or not, then of course any Linux distro will do and there is hardly any need for a new OS, let alone one that the EU has developed.
I was assuming, in the context of the original post, that the EU lacks in innovation with regards to operating systems and tried to explain why it is hard to innovate in this area because of the application barrier and due to the fact that viable alternatives like Linux aren't competitive enough.
