I think there following the footsteps of what the btc made which is the first the creator released here in this forum and the creator itself made this. The concept and the origin of how the decentralized projects launched is come from this forum. They also need founds to release there project so they offer ICO, ITO and other concept to conceptualized there project and to raise funds so there project will have a prototypes. Unlike Paypal, Alibaba and other companies they don't need it. We are in form of decentralized and it's uniqueness makes cryptocurrency different to existing brands.
