It's mostly the same trust factor as Chromium or in general Apache-, MIT- and similarly licensed open-source software has. It is not the same trust factor as Firefox or in general GPL-, MPL- and similarly licensed open-source software has. The latter, so-called copyleft-licenses, actively prevent someone from adding closed-source code to the open-source code-base or to relicense the entire code under a less strict license. Vivaldi's license does not. They could start shipping non-readable code at any point.
