Facebook doesn't take Bitcoin, its the payment processor that provides a option to accept Bitcoin. If the operator don't check the option to accept Bitcoin, Bitcoin still wouldn't be accepted. The title is misleading.
I'll be honest I put the title as Adyen will accept Bitcoin and I noticed about 3 people read it over an hour. I thought it was worthy of people seeing so I changed the title which is slighty misleading and about 50 people read it literally in about 2 minutes. Anyway I changed it to exactly reflect the story.
The fact is this is quite a big thing that is bigger than FB and includes a ton of other major retailers. The payment processor is dealing with 25 billion! annually in transactions and is growing rapidly so it is not a small story that there is now a lifeline into these markets. And its going to be an interesting story to follow cause as the article says many big retailers thought Adyen can now accept Bitcoin without any effort so they will have to refuse Bitcoin on grounds not based on good business cause I'm sure any retailer will be happy to take peoples money if it means zero effort to them but potentially increases sales. The question now is why wouldn't they?
Potentially its a backdoor for Bitcoin to the mainstream.
