There are 2 sides to consider.
If someone invested in a company, it is always wise to know the financial situation, etc of the company. And not only "here are the dividends of the year". It helps to make a decision (to leave or not)
Now, as a customer (if I was one of them), I don't think it's something I would care. If the company makes fewer incomes it's not my business. What matter to me is my money and nothing else. Now if the company is bankrupt, getting hacked, or whatever event. I would hope to be enough sooner alerted to move my coins out of the system.
So more confident, not really to me...
Need to be said, nowadays Coinbase is a very solid company, and as much as going out of business and/or the need to use the coins owned by people is close to nothing.
The statement about the fact that the company could use people's coins in case of bankruptcy. Coinbase had no choice since it was to follow the SEC. (as i was saying in the other thread)
