It's not a strawman. Literally we're saying "you see TrustCor CA didn't do anything wrong by the books, but we can't trust them anymore because they can't articulate their corporate structure on demand after scandalous allegations". Well, I simply ask people to consider how any other corporation in the same situation would response. My bet is they'd also be less than forthcoming. And my example is Apple, who we know exploits tax loopholes via complex corporate governance structures, who everyone seems okay with trusting. It just doesn't make sense to me.
Apple is a public company and it's very clear who owns and who controls the company. They're a multinational company that consists of multiple legal entities, and it's generally not a secret who you are doing business with.
TrustCor is a company that looks like a front for a Spyware maker, and when asked about that they say: "It's not like you think, but we don't want to tell you what the actual situation is, so you'll have to trust us, it's fine! Also the spyware we were caught distributing is totally not our fault, it's from a contractor in a completely different business unit and is totally independent from our CA business, but again we can't tell you more because it is secret. But trust us, the CA business is completely legit. And the sketchy things you found were all the idea of a guy who passed away recently, so we unfortunately can't ask him why he did it, but it's all legit don't worry trust us."
