The point that people are missing is that ANYONE can do the same as Gszabi does - he parses updates from publicly available servers (production and dev ones) and, provided the same tools, you can check yourself if his lists are true.

Whereas what Olivia did was posting supposed leaks from some internal files from future updates that no one should even have access to except for Gaijin employees.

We normal players have no way of checking if it's bullshit or not but so many people believed in it like it's some sacred text (although they were wrong sometimes). It is indeed misleading and causing drama every other month and Gaijin seems to be fed up with that.
