You see, the point is, "privately owned companies" just mind their own business, and are not up to pursuing people, throwing them in jail, executing them, etc. In fact, the "companies" that you should avoid giving out your personal information to are dictatorial governments/regimes that do have resources to ruin your life and feel like using them all the time.
PS. I've been constantly hearing from you the same thing repeated hundreds of times, like "everyone is waging an informational war on Belarus, etc." But why do you think they picked that country in the first place? There are some around it that are not NATO or EU members either. Let's say Ukraine. But the "informational war" is only being waged on Belarus. Doesn't it make you think there MIGHT BE something about it?
