I have the history of this site backed up at least monthly to CD-ROM back to when it went online to the public with a domain name on 5 January 1996. While I will admit we did break some rules on copyright from time to time, there was never a profit motive in any of it. The site has been - and still is - something I don't make a profit from.
While we have gone off on weird topics like "...How to Find, Clean and Cook Roadkill..." tangents and such from time to time, yes - I do believe that visitors here are here for educational and/or research purposes.
When I posted "...And, you ARE using them for educational purposes, aren't you???..." I was serious. While some 'fun' goes on here in the forums, it's pretty much people looking for answers. I have even included the statement just above the agree button for new users signing up. Well, the wording is changed to say you agree you want to register beause you are seeking educational and/or research material, but you get the idea.
One of the problems in all this is the site is and has been a 'problem solver'. That GM document was posted - what - 2 years ago - because someone needed it for their job or something. I'd really have to research backups to see. But - the point is, although it is a copyright document, it's a supplier requirement that is readily available to many people. But I guess I look at this through my liberal eyes. They'll pass it out to their suppliers for free (well, they pay in one way or another) who pass it around. In some cases a supplier is missed. Or whatever. This isn't some starving author or even a company making it's livelyhood by publishing the document. It's a customer requirement. I have a hard time understanding why they could care. Heck, they can't be afraid of a competitor getting their hands on a copy. Too many companies do business as Tier I's to several auto manufacturers.
In my liberal eyes, the only justifiable point was that the document was not the current version. To that I say only that we went through the discussion in the other thread about 'abuse'. If someone downloaded that document and assumed it was the latest version, they're being stupid. If the document is important to their business the'll have a direct connection - with Ford it's their "FSN" network.
I really think anyone downloading the document would be a case of something like where one got wind of a requirement or something and wanted to do some preliminary research (yes, research) on what it is and is about. Usually middle management types or technicians who aren't right in line to get the document until 'further down the pike' so to speak.
Yes - I can honestly say I view this site as a site mainly for research and education. And since only 12 people have actually bought 'Members' access, and 6 or 7 bought 'Premium' access, I can guarantee you the site does not pay for its self. Most people come here for free information - like going to a library.
This applies to everyone but Al and energy. They come here solely to harrass me because I'm a liberal...

Of course, if I was a conservative, I'd charge everyone to even get in the door....
