The big services are somehow all against Bitcoin
They dont want anonymous transactions etc, they are free because they want to get your informations
The banks & credit card companies have some serious lobbyists in their pocket. I am sure they are manipulating bitcoin acceptance behind the scenes to protect their precious cash cow.
Honestly i dont believe they're scared of bitcoin the way u think they may be. For them its just a passing thing, until its proven to be otherwise.
I believe the main reason for big services to be against bitcoin is simply because their clients and bussines still have no major interest or profit from accepting bitcoin.
When you look at google and facebook, they're huge companies that have massive development departments of their own, bitcoin is nothing that would increase their value or volume of their bussinesses,
it would only allow them to take a hit if the project backfires on them.
Its not allways some conspiracy/lobbying at play, sometimes its just about lack of interes, or profit to justify a move like that.
