Bear with me for a moment: I firmly believe that in order for good .com domains to be available for a smaller price the registry fee should be far higher. The reason for that is speculation: even though a .com registration is dirty cheap, getting a decent .com domain is very expensive because for many companies it is worth it to keep the domains parked, and when someone wants to buy one of them it gets very expensive…
This is a case where efficient markets mostly apply I would assume. Sure, I'd reconsider if I'm really going to ship this dream side project in my lifetime and I may drop some of those domains, but if they're good, professional domain resellers will snap at them before you get a chance.
And if you think that $10/year is too cheap, what makes you think $100/year is closer to an optimum? Why not $1000? I don't want to get into politics but this is a universal problem.
Actually, I wouldn't be surprised if this makes things worse. Raising prices evicts small domain speculators from the game and concentrates the supply into fewer hands.
This is a money grab. No one in charge intends for this increase to make things fairer. I don't think anyone looking for a domain name should rejoice that taxes (going straight to for-profits) got higher.
