I realize how this sounds, but I just don't like the idea of signing up for a "free" trial when I have no intention of keeping that service. It just doesn't seem ethical, for lack of a better word.
But, (and this also makes me sound nuts), I don't have the same objections to using an illegal streaming site.
short story - back in the mid-90's, I was living in Iowa. My cable TV was all messed up. kept calling for a service man, and finally the company sent a guy out. figured out that the cable from my house to the nearest pole was too low, and squirrels were jumping from trees onto the cable and chewing on the cable, causing signal loss. True story. So the guy replaced the cable, but when he hooked me back up, suddenly I had free HBO. I was ticked off because they had taken so long to come out and fix the problem, so I said bleep it and watched free HBO for several months until they figured it out.
