> I realized not only did I not want my work to know what I'm doing on my personal time, the risk of cross-contamination and being accused of stealing confidential documents or a personal text making it look like I'm doing something wrong is too high.

If they wrongfully accuse you of that, isn't it a place you should leave in any case?

Name me a large corporation who "trusts" their employees. I'd pretty much be forced into unemployment if trust was a requirement.

I would guess you're probably right. But if you are accused of something, not having a separate non-work computer/phone could make that process worse.
