I don't see any reason why these would automatically affect Bitcoins. These target ICOs which, let's admit it, has been used for a lot of scams. It might even have a positive effect in that people would just spend their money on Bitcoin rather than buy into some shady project.
Facebook and google not ban bitcoin but they ban cryptocurrency related ads. It is not related to bitcoin. There are many ways to advertise. The biggest suporters are via from bounty in bitcointalk. It is very targeted market to spread out ICO. In the end, facebook and google ban effect nothing to bitcoin.
I actually I feel like there was no ban. I still see a lot of cryptorelated ads on Youtube. Either Google didn't include it or a ban in Youtube is down the pipes.
