Almost Totally Foss.
I'm looking towards migrating from Obsidian to Logseq MD. The official Telegram client is not completely foss and its server is fully proprietary, so until Matrix becomes good enough to try again to persuade my family and friends to use it, I'll consider this middle-ground. And for the last one, there is the banking app. I’m lucky enough to not have to use a complicated root hiding method or any Google services implementation... but a Foss banking app (No a crypto wallet) is a dream I would love to see in real life. Of course there are some propietary PWA I have to use too (Like Google Classroom) but is more libre not having them installed and discouraging their use.
Update: I enabled LibreFind to show system apps and forgot that I have a dolby atmos module which is propietary and I must replace, only that Jamesdsp sounds worse in my phone. (image updated since it use to show 93% percent)
Let me discern with you with this. Copyright actually started as a way for censorship, control and profit.
Also, trial fees are usually unaffordable for smaller business or citizens in most of the world. Corporations employ different strategies when using "someone else's intellectual property" to avoid problems or persue their suers, and usually get away with it.
