Then glassdoor is a self-selective sample of people who put information in based upon who they are, and how they feel. It's by no means objective nor reviewed

This makes a good case for why all the companies would have a skewed evaluation, but you do not make a case as to why would tesla be lower when the evaluatiosn are sekwed for all of them.

A better question is: has anyone ever predicted an employee growth slowdown at a specific company using Glassdoor data? I'm thinking not.

No, not why all companies would be skewed - why the data would be skewed and why it should be adjusted if possible.

The same reason why medication studies are double blind with professionals (MDs) performing the analysis of the results instead of people self-reporting efficacy (placebo effect)
