How far does Google go after us?

I looked through this: habrahabr.ru/blogs/hosting/72584 topic and became interested in the Tamper Data plugin mentioned in the comments (I had never heard of it before). I open Google, I enter "ta" - in the hint in the first line - Tamper Data.



I have noticed something similar in the behavior of Google before, but this is the first time when communication is so clearly seen.



On the one hand, it is unusually convenient, on the other, it scares.
