It's just noise. I've used them for years with no trouble. Regarding getting money out you can't beat coinbase as they have an instantaneous payout to paypal. And i can guarantee you that your HSBC account won't block payments from Paypal
Just get a binance account and you can buy directly from your UK bank card. To cash out, send to your coinbase account, convert to GBP, send it to your paypal account and then back to your bank account. job done :)
