Keeps getting worse

I have been working for Amazon for more than 3 years now and the culture keeps getting worse. Amazon is supposed to be a data-driven meritocracy, but after they figured out that so many managers were abusing the metrics which are supposed to be used to measure performance, they removed a lot of the metrics like in the tech survey or anytime feedback. 

This made all skills measurement more "soft". Are they that stupid to not realize that this just makes everything more subjective and easier for managers to manipulate? 

Amazon today is all about politics, empire building and career ladder climbing without much focus on actual real success in projects, operations, or anything else. No wonder I'm an Amazon old-timer at only 3 years...
