Proves Einstein right in what way?
If I say that below the surface of earth there are green goblins who suck down objects from the air and then an apple drops from a tree - that does not prove me right. It just does not prove me wrong.

However, this doesn't open the floodgates to any old theory because a simpler theory that explains the data is preferrable to a more complex one. Your green goblin theory might fit the data, but then leaves open questions like what do green goblins eat, why were they not detected previously, what else might they affect etc etc.
Apples and goblins should produce predictions that differ from existing theory, and predict a new type of observation that could confirm its correctness versus existing work.
It provides evidence that his theory is correct, it does not prove it because they still could find evidence that does not fit general relativity.
The posters example made it sound crazy, but "proof" is the wrong word to use. I much prefer the paper's opener of
>The theory of General Relativity (GR) continues to pass all experimental tests with flying colours
Modern scientific authority derives from a inheritance of proofen right, which people who hang around in online communities usually do not know about. Add to that the "progressive" tendencies to smash the "old" - now taken over by the alt-right and you get a ahistoric bunch of fool, who would throw dirt at everyone no matter how right or wrong his hypothesis was.
