What non-FOSS software are you using that you wish you could replace?
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.
Pretty much anything on my phone. Though I have recently found f-droid, and through that I found Phonograph. I wish open street maps could replace google maps, but I really don't know what it's trying to do.
Depends on your country, but where I live Open Streetmap is better than Google's map. I hear OsmAnd is a great app, but I don't use a smartphone so I haven't tested it. I just know that their very compact offline maps are impressive.
You should also check out Droid-ify if you like F-Droid. Has more sources, notably those apps on Github which aren't on F-Droid. Since it can grab apps from Github directly, it gets updates much faster than F-Droid.
