I'll venture to say this is the case. Most tech firms are small-fries when it comes to evil.
Cargill, Monsanto, and pretty much any oil company - now that's serious evil. And that's just in recent history. We're not even talking the East India Trading company.
Wake me when a tech firm profits billions through sweetheart contracts on an unjustifiable war or, through ineptitude or malevolence, kills tens of thousands in an industrial disaster.
