Unlike you, it's the open-source parts of Vivaldi I'm most afraid of. I trust them to support their users and I believe they desire to have users who trust & respect them.
I don't trust people who are more code-savvy than I am (that's most people) not to insert or exploit weaknesses in open-source software or other open code. With closed-source software, I know the origin point of the software I install, I know the names of the individuals or teams who developed it, and therefore I know who stands behind it, because their reputation is based on that released software working. If something goes wrong, I can take clear action because I know who is to blame, e.g. Vivaldi, Microsoft, etc. With open-source software, that liability for the software developer is thus offloaded to "the community", and users have no viable recourse - meaning that attacks on open-source software are a lot safer for the individual attacker.
I support 100% closed-source development and extended release schedules. Open source & rapid development / release scares the daylights out of me. Too many people can see it, too many people can make changes, and it's happening way too fast.
