How about all tech backdoors are bad and we should aim to use and make software and hardware that is ethically produced and usable without selling out your privacy and security?

You’re being disingenuous, for example by equating the cybertrucks and some other Teslas being “destroyed” (sure in some cases but not by slices of cheese or notes) with any and all electric cars, or by equating the negative sentiment against Tesla with negative sentiment against any EV.

It is still a good reason not to use Ecosia, however.
