I've read the post and it's just for BTCBTCBTC sells. I'm pretty sure they'll pass the fees on you. I see no issues with that because it's just transferring your money on coinbase to Paypal. If it was the other way around, that's where we'll have issues.
You mean to say PayPal will limit everyone's account who are selling bitcoin at coinbase and not limit coinbase's account because they're buying bitcoin?
