Wow, I was sure all donkeys and mules died a decade ago. Or were full of malware.
How is this still usable today? I mean you can find literally everything online for download or stream, without pirating over p2p.
Depends on what you're looking for, but "literally everything" is not available to download on clearnet, some things can only be found over p2p via groups you'll get invited to/know the right people. HTTP/HTTPS/WS/WSS is also still blocked in many places today, or otherwise tampered with, while p2p presence remains strong in those locations.
I haven't used eMule in maybe 15 years but I still torrent a lot. I find that it's massively more convenient and reliable than shady streaming or direct download sites. You just have to find a couple of reliable trackers to get your torrents from. I have a dedicated seedbox though, I suppose that if you download from your home network it could be more annoying.
Just as a very silly example: try to find Pantera's glam rock albums and you see how much the mainstream channels feed you only what they want you to see and consume.
Maybe they added now or it can be a regional issue, but they didn't have it in Germany at least until 2018 when I looked for them because I wanted to show a co-worker.
