Of course, in some countries you have lack of important freedoms, which says a lot about their state of democracy. However if your country gives you a choice, consider using it in order to not lose it.
It's nice to know that I'm somewhat famous. I never suggested that running banking apps on GNU/Linux phones was as easy as on Android forks (however, reportedly it is possible for some banks). I meant other daily tasks of course.
The country I live in has strong consumer protection laws. Banks deal with it by judging risks: That which is too risky is what they won't offer.
My bank does not offer Western Union transfers, for example, because there's been too much fraud. And does not accept root-platform devices as 2FA "something you have" factors.
Liberty or consumer protection? Your choice, really.
Arguably, typical Android is less secure than a Linux phone, since it constantly calls home, runs a ton of untrusted apps and often has a short software support time.
