For me its honestly a ton of my work software (digital forensics), shit is too niche to be replaced by good FOSS options. Cellebrite, Magnet Axiom, etc. Autopsy is great and free and has a linux version but it simply cannot get the same level of data without a pretty nutty level of custom code.
And the biggest side effect of this is FUCKING WINDOWS. God I would replace this nightmare OS in a heartbeat if the aforementioned work software would make linux compatible versions. We have legitimately wasted 10k hours dealing with windows bullshit that would not be a problem in linux. Though im sure linux would take a different 10k for its own problems.
What about you guys? Doesn’t have to be work related, thats just the thorn in my side right now.
Since gaming on linux has made ridiculous improvements im running it fulltime on my desktop machine. But I ran it on my laptops as sole OS for about 15 years now.
For router firmware i bought an archer c7 v5 last year (50€) and am running OpenWRT now. It’s sitting behind my ISPs router, but for that i don’t care.
Banking App would be really difficult since this is a huge security operation with liabilities. And discord would be nice to replace since it just fucks you and steals your data without giving it a second thought but there is no conpetitor i know of.
