This kind of dangerous logic is how you end up with anti-vax conspiracy theories about Bill Gates and mind control, about how one could trust Pfizer’s Phase 3 vaccine trial data they submitted for approval, etc. On the one hand, yes of course: sources matter and you need to consider whether anyone has a motive to mislead, or even merely a motive to not dig too deeply into a claim they might wish to believe. But on the other hand, a company merely merely being founded decades ago by a someone of a particular nationality does not on its own constitute strong evidence that any claims about that country are tainted or self-motivated. That connection is just too weak — you need to bring other evidence!
