I have never paid for cc. I've always felt that it's something I don't really need, so I'm not going to spend precious dollars on it. Plus even way back when I first started downloading, I could see that T$R had nothing worth downloading, even less worth paying for.
I have donated to certain free sites now and then when I had a little extra money. Recently, I went to Adele's site and found she had run out of bandwidth. This was unacceptable to me, so I immediately sent a donation to WNF. It wasn't much, but a couple days later Adele was back up, much to my relief.
That's how it's supposed to work. If a free site has quality cc, the community will support it with their monies when it's needed.
