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.
Photo editing software. My wife didn’t want to pay for Lightroom anymore, so we switched to a software with a one time payment, Luminar. There are some FOSS alternatives, but none of them have been a hit with her. All of them are missing something or are intended to compete with a different line of product like Photoshop, Illustrator, or ProCreate.
