Are they offering any type of discount for bitcoin use?
Why would they give discount if they have to pay a fee to the BitPay similarly as they would pay to PayPal ?
Also, even if they processed the Bitcoins themselves, they would still have to convert BTC to dollars anyway, so there is another small loss in the process of exchange.
Assuming that BitPay and Wordpress are well-managed (big assumption), BitPay is giving Wordpress a significant discount on its advertised processing fee, and Wordpress is passing part
of the savings on to customers.
[It is also possible that the CC cartel interferes with this. Funny thing about bitcoin libertarians. They like cartels, but cartels fuck them anally. Does this mean libertarians are bottoms?]
If wordpress does not do this, then bitcoin will not be used by a meaningful number of Wordpress customers. If bitcoin is not used by a meaningful number of wordpress customers,
then bitcoin adoption will negatively affect wordpress' bottom line.
Payoff = Additional Margin from Bitcoin Payment vs. CC (negligible without volume) + Additional Customers who can only access bitcoin (absolutely negligible) - Adoption cost
This will be negative unless a discount is offered to increase the volume of BTC payments.
To sum up in different words. BitPay claims that the CC companies are taking 11% on some wordpress payments vs. ~3% via BitPay. Wordpress should introduce an incentive for customers to use bitcoins so that
it can earn larger margins. Otherwise, what is the point for Wordpress? Customers are not going to use bitcoin for the hell of it. I don't get any miles when I pay with bitcoin. Unless there is a discount, I pay with my card every single time.
