The thing is, ownership of any of these can change at any time. Bitwarden, Mullvad, and Tutanota could be sold to very different owners.

That is up to and including something like uBlock Origin, which only has one developer, and would suddenly be very different if that developer died and the project had to be forked.

You can never trust that the person who takes on the reigns has the same ideals as the people running them now.

Hell, Mullvad was abused to the point they removed access to Port Forwarding on their VPN service, which has led to many people needing to switch to crummier, shadier VPNs that still offer port forwarding access. That’s not Mullvad’s fault, but it is an example of them having to change their philosophy and what they offer because of abuse.

Trust should only go so far, and loss of trust should be very easy. There’s not a good reason to keep “trusting” something when it has fundamentally changed from its initial ideals.
