>>"Fine, but those who purchase something want something they can keep. Big Content tries to sell the same thing over and over again, rather like prostitution."
Really? When? Selling you DVD's for movies that you previously had on VHS? DVDs were way better than VHS and nobody forced you to buy. Selling Blu-ray versions of movies you had on DVD? Don't think the upgrade is worth it then don't buy it. For others, the noticeable jump in quality was. "Big Content" may try but unless they're actually forcing you to, then that's their right. Blu-ray to HD w/ HDR? Again, nobody forced you to buy if you don't think the quality jump is worth it to you.
Honestly, if a movie means that much to you that years after seeing it you still feel the need to see it still more and with higher quality, then pay. It's a different product. You were happy with the original quality. If you're no longer happy with that quality that doesn't mean you get the work and production costs that go into the latest release of it. This is a very frail argument to call buying a product a "ransom". Nobody can ransom something to you that you don't own and don't have to have and owning a crappy VHS copy of something doesn't mean you "own" the lastest remastered DVD.
