Not really a question about whether I trust other devs. It's more that these devs admitted to causing harm, and seem to think fooling their users is a good idea. Then when called out on it, they say, "people need to relax, just a joke bro, better be careful next time!" instead of just owning up to it and hopefully move on.

Installing firmware onto thousand dollar machines is stressful enough, they shouldn't be "taught" a lesson just because the developers thought they should.
