It's too late to gain trust from people. The delete Coinbase movement has already started and I think it will go quite long. It's interesting if they admit their due diligence is lacking while people who spent just 10 minutes browsing can know why Neutrino is shady, or at least have a lack of ethical ground. I believe sooner or later this issue will be forgotten, but Coinbase for sure won't gain trust from major users.
