Nothing else really matters, how much they've earned through transaction fees, how long they've been around, or how many people have been using them for so many years. The actual point is that they find cryptocurrencies to be a threat to them since they know they are going to be replaced by them, and that is the reason why they are doing their best to make people think that they are supporting cryptocurrencies so that people don't leave them and just use cryptocurrencies.

Whether it's Paypal, banks, or any other financial institution, they all can see the constant growth of cryptocurrencies, especially Bitcoin, and they can't just sit back and see their own downfall and all these things are actually a reaction to that since they fear losing control over the finances of people.
