They do have the user's back. That means not wearing a tin foil hat. In order for a modern browser to work in a halfway decent manner, they need to ensure that things are reasonably up to date, that developers see crash reports so they can discover bugs and security flaws before someone malicious does, and that lists of malicious sites get updated. Not checking for updates, not providing bug reports is the opposite of good software hygiene.
