It was just a matter of time after the Google ICO ad ban, that other big companies will follow.
It is not a bad thing, as many ICOs were scam and even most of the honest ones will not succeed in the end.

How will the perception of cryptocurrencies improve when big companies are banning ICO- only of the major ways of selling inventions in the crypto space? How will we get to hear about the honest projects?
