GitS:SAC OPs and EDs

Now that's weird. I looked up Ghost in the Shell on the Japanese Wikipedia to find out what's up with the song "GET9" which is listed as a TV size version on some (one?) of the soundtracks. I thought maybe there was a rights issue with GET9, and they had to shuffle things around. Well, apparently both the first series and 2nd GIG had different OPs and EDs depending on whether it was for "terrestrial broadcast" or DVD. (Satellite?) I can't say I've ever heard of such a system before. Anyways, that explains it.
Unrelatedly, I'd like to make a request to my computer to stop repetitively disconnecting from and reconnecting to my mouse. I suppose I should really run some tests and find out where the problem is, but I'm lazy.

borrowing vs. downloading

Out of curiosity, do you guys see a difference between borrowing licensed (and available) DVDs of a series from friends and downloading fansubs, or even DVD rips, of that series?
I guess I've come to see watching and buying as separate activities, and although I support anime financially as much as I can (some would argue more), in my mind if you're not financially supporting the industry... What's the difference? I guess to put it bluntly, I would go so far as to say that if you think downloading the series is unethical, you should extend that logic to borrowing being unethical.
I do realize that things like Netflix are another option, better than either borrowing from friends or downloading subs/rips. But that's not really the question I'm asking right now.
I've also been thinking lately... Is shopping around for sales/good prices being a non-supportive consumer? My sense is yes. If we show that we only want to pay sales-type prices, their incentive to publish (quality product) will be lowered even further.
So, yeah, opinions wanted.

Also, seeing the X Files movie with my mom (and Allie, for a surprise) was quite nice.
