It is essential for the Web Vault page to be clean, and it is.
I have previously tried to make a case for removing trackers from the online password generator page.
Has anybody checked the account registration page? I assume that one is clean as well, but if not, that should be remedied with high priority.
With the above exceptions, I don’t begrudge Bitwarden the use of trackers and third-party cookies to further their business purposes, as much as I disdain these practices. However, I agree that it would be preferable (and a better look for Bitwarden) if they used open-source analytics instead of Google analytics.
