Yes, I'm aware that unfortunately Wasabi have sold out. I've told them exactly what I think about their behavior already:

Absolutely. Don't even get me started on the clusterfuck that is BitPay. This is why the best solution is for merchants to use their own self hosted processor such as BTCPay.
Coinbase, Binance and similar sites are so popular and will remain so because they allow users to buy/sell with less friction than the alternatives.
Depends on how you define "friction". I would say requiring me to give them my name, address, phone number, employment status, information on where my money is coming from and where it is going, copies of my passport and driver's license, selfies, and copies of my latest colonoscopy, to them have to give up custody of my money and still risk being locked out my account and waiting months for support to get back to me to be far more friction than simply finding a well rated user and trading with them directly peer to peer.
