Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
I am disappointed we still don’t have a solid FOSS smartphone OS that can compete with the 2 monopolies who have cornered the market.
I don"t want ro sell my soul to Google or Apple just to use my bank (even on my computer thanks to mandatory 2fa apps) or to renew my government issued ID or to buy a train ticket on European public transport.
That disappointment isn’t with Linux
depends on where you draw the line.
in the past, i’ve been mildly dissapointed by the drama-queen-esque antics of the kernel developers; but i most recently DEEPLY disappointed by how thoroughly the kernel developers to caved to the us gov’t’s demand to kick out russian developers instead of complying maliciously like others do.
both are separate from linux, but linux can’t exist without them.
postmarketOS, LineageOS, GrapheneOS?
I know they have limited hardware support but that’s only a matter of involvement at the end of the day
