For me it always was.
Without upstream there used to be no downstream.
I've noticed this too, and it is pretty easy to test. I tried capping my upload speed at 0.0kbs or even 0.1kbs and while this is possible it always tanks my download speed to somewhere near 50kbs. Once I lift the upload cap the download speed jumps to over 1mb/s.
All in all you will only upload around a couple hundred megabytes but it seems that in Germany its not about how much you uploaded, but that you uploaded.
Torrenting isn't worth the risk to everyone, it doesn't have anything to do with paranoia. It has a small risk, greater if in Germany apparently, but it is still a risk.
I still think watching a review video by a youtuber is a much easier, faster, with absolute 0 risk, way to see if a game is decent.
