What I can't stand are these partnerships HW wallet manufacturers enter into (Ledger went way overboard with that), and even some software wallets like Trust have done it as well.
I don't like it either, but I understand why they do it from a business perspective. Why have the users move the funds they want to exchange from the hardware wallet and into a third-party exchange if we can create the same type of service and have them do it on our terms? Plus, we earn a small commission from it. I also don't buy the marketing hype of how it's cheaper than doing the swap directly through the 3rd-party exchange.
