The project has the right to their campaign, if they wanted the participants to be KYC-ed at the end of the campaign it is not their fault if you don't want to but you're not going to take any from the allocation. Here is a BUT, the announcement of having a KYC should be done in the very first place to let the bounty hunters know what are they giving in exchange for participating, which most of bounty hunters don't like to get KYC-ed.

With cryptocurrencies, I believe that it was created to eliminate your identity online which is somehow defeating by the KYC procedures.
