Hot take: we're better off without the type of people that is convinced by argumentum ad hominem.
Because. Let's pretend for a moment that the coders were hypothetically the long-lost children of Cruela de Vil and Emperor Palpatine*. Even then: it's still open source, so someone who's extra distrustful can audit the code and compile it by oneself, and create an instance that does not federate with lemmy.ml or any other here.
*Sorry nutomic and dessalines - it's just for the sake of the argument.
