Accepting fiat is something all icos should do.
Back then they weren't and that was wise. Because they were getting ether when eth was 300$ and when ico over it was becoming 1000$
Right now it is the opposite, unfortunately.
Sorry but I disagree with you, the point of an ICO is to exchange coins for coins ( when we talk about ecosystems like ethereum and Neo, tokens) or else you can just search for VC or post your project on kickstarter
