That is the point. It is true that the script for the unique UI that Vivaldi has is proprietary (about 5% of the total), but it can be modified by the user to adapt it to his personal preferences, there are even threads in the Vivaldi community that teach how to do it. There is no reason to suspect any code that has malicious functions in the UI. It is not the same as in Chrome, EDGE or Opera, with completely proprietary and non-auditable layers that go far beyond the mere UI and where no one can verify their function without reverse engineering.
I think that OpenSource is important in new products that allow shared development, but OpenSource should not be confused with reliability, privacy and security, this has nothing to do with it and only depends on the ethics and intention of the Devs or the company, apart from the value of OpenSource in a product whose market is more than saturated with more than 100 browsers and forks and another 70 already abandoned, is quite debatable.
