While those examples do use the passive voice, the passive is not the real problem. "These events impacted seventeen of our teammates" is the active voice, and it is no more forthright. "Mistakes were made by Bob, Sean, and Susan, who have been fired" is (if accurate) quite clear about assigning blame while using the passive. It's true that some people overuse the passive, and for those people noticing and considering whether to rephrase can produce better writing, but insisting on forgoing the passive entirely probably won't. If we want to prevent evasive writing, we should look for and call out evasive writing, whatever voice is used.
Right, the active construction does grammatically require we put something there, where in the passive we get to omit it, which is why the passive is sometimes used for evasion. But if you're interested in whether someone is being evasive, just... look at whether they're actually assigning agency appropriately. Grammatical form doesn't answer that.
