My experience is that just seeding what you like indefinitely is not useful. You have to be proactive and find popular torrents to seed and accrue any meaningful upload amount.
The tracker I use has a bonus point system to encourage all seeders even of unpopular releases but it's slow.
I found that the perfect solution for my use case (music) ended up being Soulseek. I don't have much money for seedboxes or buying extra storage so I feel like I'm priced out of private trackers.
I think the main pro of this system would be that it requires no trust. The immutability would be actually a con for privacy: if you're burned or doxxed later, there would be hard evidence of your identity in the blockchain.
My opinion is that what matters is how much money each part of the network receives.
For example, instances tend to be transparent about their funding. And we can see that some of them are just months away of being out of cash. Meanwhile, we see people subscribing(!) to a very expensive app that charges $20 to remove ads (and tracking and data collecting) otherwise.
I think is okay to keep people aware of these things. Getting defensive about it is just a waste of energy. For both sides.
Why not go full data nihilist and say that every file is just a natural number expressed in binary.
