Is it corporate greed, arrogance, indifference, or some other reason that compels a company to essentially "stick it" to their customers?
Have they broken their contract with you? The contract you agreed to at the time of purchase? If you've changed your mind since then, aren't you free to sell your license to someone else? Greed would be if VSL forced you to buy their products against your will; so this doesn't look like greed to me. Please learn not to sign contracts you dislike; this should solve your feeling that companies are "sticking it to you". When you buy a product, you don't get a slave you can order around; you only get what was in the agreement.
VSL could add value to their products by adding insurance against lost/stolen keys.
