I use GrapheneOS too. Most of the time it works great, with some weird bugs around group messages and needing to restart every now and then to get to a fully functional state between the browser and keyboard properly working with each other and the network connectivity going away. I do enjoy full control on network connectivity and notifications.
But beyond whether the OS is good or not, "fuck you, I've got mine" is not only sad as a position in general, it is also a bad tactical choice, because over long enough timeframes you can't assure that you can keep yours if others are deprived.
I agree about "I got around the system so I don't care how bad it is.", but it is at least still a form of saying "an alternative to this problem is Graphene", and that can't be repeated enough until a whole lot more people are using it, or anything else like Lineage.
Graphene (or anything else) will only stay a useful option if a whole lot more people use it so that government agencies and banks can't ignore that many people. A whole lot more people need to feel they aren't completely alone if they thought about using it, that it's actually a real option and not a kooky crap option.
Right now agencies & companies can totally ignore them all, and everything that still works today is just luck.
I haven't used Graphene myself. At the moment I have a stock rom that's merely rooted using the official manufacturer supplied bootloader unlock, and my small local credit union bank apps work, and the LG app that controls my air conditioners and microwave does not. Even if the bank apps didn't work it wouldn't matter because they have working web sites, and I never wanted an an app for my appliances in the first place.
But any day that could change.
It's just luck the banks have web sites that work in firefox on linux, and just luck there are no functions I need on those appliances that require the app.
