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.
For me it’s Adobe After Effects. Yeah, I can do most of what it does in a combination of blender, natron, gmic, etc… but I really like the workflow of AFX. Not having that tool was one of the hardest parts of cancelling my Adobe subscription. Nowadays I would even settle for a non-foss alternative. As long as it’s running on Linux. But so far, that has not happened (I use other non Foss tools that work great, like resolve/fusion and Houdini… but I still miss AFX)
Edit: yeah, I missed a detail in the question: I do not currently use AFX but used it a lot in the past and am now trying to replicate workflows I based on it with other tools… still miss it a lot and would give a lot to have a solid alternative…
