I think some of the internet platform start to ban cryptos. Facebook is only trying to protect its image and reputation. I do not know why, maybe because of the ICO reputation. This move will definitely cut down on scam ICO's however at the expense of  genuine ones. To be honest, btc has nothing to do with ICO. There must be an alternative in situations of this kind. If you want to invest into something certain, there is no such thing like that. The fact is that initially Facebook was created as a social network for people to communicate. Just invest into land or house. And today social networks use as advertising banners. But I think crypto will be more people. Apparently it's someone who is annoying. We do not need facebook.
