Problem 3 has another effect. There's a whole industry of conspiracy theorists who will point to that paper to give credence to their own BS, while they create Youtube videos and wild pop-sci articles to influence the general public on whatever their agenda is.

I have a friend who recently has 'taken an interest in science' and is now passing Youtube videos all of the time that are total crap, but make reference to 'scientific' papers. I 'learned' how earth is already doomed because Betelgeuse went supernova, and that there are deep shafts below the pyramid of Gizeh that only an alien race could have dug. Stuff like that.

Net outcome where it comes to science may be that this helps erode people's trust in science.
