This guy has it right, and he has so much experience with this, which is clear through his obvious frustration. I completely agree with him, though because I'm half his age I'm a lot less frustrated. He's not being completely asinine; he even says he supports artists giving their time for charitable work for nothing in return.
A lot of what he is reiterating reminds me of this blog I read once, linked below. I'm pretty sure someone from Newgrounds posted this here:
Basically, if someone is not willing to pay you or give you an absolute offer (being, if we use this, we WILL HIRE YOU), etc., then they are not putting value on what you do. It's tough because a lot of artists truly do enjoy creating, but what non-artists don't understand is that it isn't always fun creating for others. Just because you are skilled at something doesn't mean you owe the world your skills. I would never ask a chef for free meals, so I could "try out his food, to see if I even like it." I would never as a mechanic to fix my car for free "because you are good at it and must always enjoy it." That would be ridiculous. Not to mention costs of supplies. Art is not only time, but initial costs for materials. To make Flash animations you had to buy the proper software (yes, I know, some of you pirated).
I think his moral is not to let people take advantage of you. Just because you have taken the time to develop a skill doesn't mean you owe anyone anything, particularly a business that should be able to pay you something for your services. If they valued it, they would. It's as simple as that. If they can't do it themselves, they should pay someone else to or offer guaranteed future paid jobs at the very least (even though I am suspect of that if they aren't even initially paying you).
