Honestly, it doesn't make a difference with the traditional investments and finance system that a third-party is buying and hodling your bitcoin on your behalf. It still avails the middleman in the process which is what ought not to be with bitcoin adoption where the individual or investor buy and take self custody of their bitcoin in a noncustodial wallet.
It can't be helped; the bank saw a profit in engaging in Bitcoin "services" and as a business entity, it is normal to take advantage of the opportunity. We might see more and more banks act like this. They were leashed when the government and financial institutions had not laid a regulation on Bitcoin, but were released to take action when Bitcoin was legalized. This might not be an individual adoption, but it is a corporate or institutional adoption, no matter how we call it, being centralized or whatever.
