You have a point because some of these ICOs do not meet expectations after having a successful ICO. However, not all ICOs follow this trend, there are ones backed by experienced team members and a good product which is highly in demand. Projects like this are very difficult to hit back to zero.
Some may find the ICO which is nice, but for now, everything is really falling and no one could have expected. This could be also a scheme planned by others to take profit. for now, only time will be able to determine if this altcoin and ICO will be satisfactory or not for the long run later as the time before.
