You might want to read my other comments elsewhere on this post.
Please keep in mind that no matter what technical measures you take, accepting Epic’s “free” games requires agreeing to their terms and conditions, which they can change after you get the games. I really don’t recommend it.
Trying to discredit people because of the forum on which they discussed a topic, or because you view them as beneath your skill level, is a more than a little misguided, and frankly, disingenuous.
Epic themselves have admitted to copying Steam data and scanning running processes, as has been documented in various news articles. (example, example)
In any case, the point is not one particular incident or report, but rather that they have the capability, grant themselves permission to use it via their policy documents, and have earned distrust among a lot of gamers. Posting condescending emoji here doesn’t change that.
Edit: P.S. In future comments defending Epic, you might do readers the courtesy of stating up front that you are moderator of an Epic Games forum.
