To be honest, existence of the ICO itself is a wrong thing but what can we do about it if its getting invested anyways.
Well, these days ICO's get extended because there are too many of them and thus it becomes hard for the ICO's to collect the sufficient investors that is needed for the project fund allocation and thus if it is not done within the specified timeline then they have to extend it. If not done like that, then there will be no proper fund raising and thus budget allocation to different process may collapse. So they have to do it technically and thus as business its nothing wrong in that.
