If it's true that Microsoft is no longer underwriting the free version, I don't think it's unreasonable for Telestream to charge for it now. For those who think it is, when was the last time you did any useful work for nothing? You are, of course, free to not pay for the updates and to use another tool - or the last free version of the Flip4Mac player - as you see fit. But bad-mouthing the developer for wanting to be paid for his work is mean-spirited and wrong-headed. As for money-grubbing, like I said, when was the last time you did any significant work for free? If you are, like most people,, paid for your work, then you are describing yourself when you accuse Telestream of money-grubbing. Get a clue.
As for Perian, support for that was dropped years ago, probably because developing a free program was unsustainable. As for others, like VLC, that remain available at no cost, the developer no doubt has alternate means of paying the bills - means not available to everyone.
