"I have not looked through the 5 pages of posts, but I sincerely hope that "selling" means inclusion of the demo in a magazine. If they are actually charging for a demo, thats just stupid."
They are selling it through amazon, as well as distributing it on a magazine, which is what happens with many demos. It's just the "for sale" versions were made available before the freebie edition.
The reason they charge is to recoup some costs. It costs money to dupe CDs, it costs money to pay for bandwidth. People complaining about paying for demos, I feel your pain, but expect to do it, or expect to do without demos. The free lunch is over. You'll either be paying for FilePlanet or Gamespot, subscriptions to cover CDs, or you'll be hoping they pop up on Morpheus (and are virus free).
"If the gaming industry wants to charge for demos, I won't buy their games."
That's a great outlook for PC gaming, because free demos are going away, kids. If the companies won't pony up bandwidth, which they haven't seemed willing to do, the download sites are going pay or are disappering.
