I believe that time will eventually show that pre-sales simply don't work to do anything but temporarily enrich the launchers.
Crowdfunding works. Look at kickstarter. Cryptocurrencies are fantastically complicated projects, that take years to develop - how do you propose the developers live while working full time on one of these projects?
That's not a good argument. If there are comparable competing cryptocurrencies and one of them is subsided by some altruistic or ideological rich sponsor or by indirect monetization and the other expects users to pay, then users will likely choose the former. File your fairness complaint with the market.
