OP: you and many commenters are making some significant assumptions. There's a great short story available online: "The Road Not Taken" by American writer Harry Turtledove that considers how aliens might arrive without more advanced weapons.
Give Jellyfin permissions to access the files there
Since you are using FAT32 which does not support file level permissions I guess this will show up as 'owned by root'. You will need to do something like this or this
I think you're missing a key area here. The original Mozilla product was Netscape- a commercial combined web browser and email client. There used to be a number of commercial competitors in the space, e.g. Opera, Eudora, etc. Microsoft killed that market in the 1990's.
I struggle to see how any organisation could make money out of giving away a product that costs money to produce and promote. You've suggested they could have been Proton but that's a completely different sector. We could just as easily have suggested they could have been Twitter, WhatsApp or Instagram.
This is a common thought experiment for lots of people and the break point is usually kids or maybe a partner. If I could still get the same kids (implies same partner) then absolutely. I could be a lot richer, more successful in my career and happier.
what you have already tried- not sure where all those flags are coming from
I would also support the comments here recommending that you use docker. There's only a small number of Linux distributions and versions where a distribution package installation of jellyfin is fully supported, but even then what you need to do varies across each one. All Linux distributions and versions support docker and the process is essentially the same for all of them.
Ok, aside from Android, I've yet to see any serious usage of SELinux in the real world and I've been working on cloud tech for years. Acknowledged issues such as complexity aside, it's really just that much less relevant in a modern, single purpose environment such as Docker/kubernetes/cloud functions/etc
I feel this and some of the other comments in this thread are missing the point. It's not about me and my followers. It's about the news sources and topics that I search for or follow. They simply haven't moved to Mastodon and where notable individuals that I follow have tried, it simply hasn't worked out due to lack of interest. I'm not interested in the fediverse as a topic in itself, I'm interested in the topics and events I want to follow. Something happens and I can find and read and watch clips about it on Twitter. Not so Mastodon.
Well if you want a windows pc app there's this. There's a list of official clients but it sounds like you already know it
