Just go through the interview taken with the Twitter CEO today. He has explained that none can stop the bitcoins growth in this world. This itself allows you to find the learn that companies not against bitcoin. It is all happening because of idiot stupid government buddy.
I personally takes this ad banning would be fine because there everyone here should come to this forum. No one will stop the crypto currency ads here and it always goes perfect bro.
L:ets say Twitter and Facebooks are one of the ways to advertise or having such exposure but we do know that this is not only the medium we can able to use.Going back into the thing being said on the OP.Its really quiet ironic. They are saying positive things on bitcoin but still decided on implementing such ban on crypto ads.Well they do have the full control of their own decisions.
