This article does not offer any proof. It's hearsay, from the title saying he "reportedly" forced it, in turn citing a Platformer article that itself also provides no proof and instead accepts the stories from fired engineers as gospel. The platformer article then goes on to say that views still fluctuate wildly, and that it isn't in line with a supposed 1000x boost. The same Platformer article then says that they believe the supposed 1000x boost is no longer in effect, but they guess something else must be in place. The Guardian article doesn't bother to mention that part.
