Eventually they all realize that they can not fight bitcoin, the adoption is happening whether they keep spreading FUD about it or not and the market is already being taken over by other companies (such as Coinbase) that are making a ton of money from the traders with millions of dollars daily volumes on average.
At the end they would want a piece of this market so that they can make money themselves instead of letting the "fees" go in pocket of another business.
Even though this was expected long before any of them changed direction but you are right that it is weird that nobody has been talking about it (which is a bigger news) when they blew PayPal news out of proportions!
Yeah, they realized that fight is useless but instead of fight, to my mind they decided to become a part of it and absorb it. Crypto doesn't need visa/master card or PayPal and in reality it was created in order to get rid of 3rd party services but seems they need it in order to get more profit. I would say that these giants see how Binance, Coinbase and others are growing and taking a lot of profit so why not to takeover them? And current exchanges that I mentioned, are nothing compared to VISA, Mastercard. This is just a monopoly, these giants won't let others to shine and they have all the resources for it.
