This trend is awful for businesses. In October 2019, PayPal (which owns Braintree) also started to retain their 2.9% + $0.30 processing fee from refunded transactions. Stripe is now in the same class as PayPal.
Square still refunds processing fees to merchants for refunded transactions. They have the same fee (2.9% + $0.30) for online transactions, and a lower fee (2.6% + $0.10) for in-person transactions with their card reader.
