It has nothing to do with how easy or hard it is to disable. The problem is that it doesn't ask first, or even tell you what it's doing. OK, now that I know about it, I can turn it off, but how do I know they won't do something similarly ugly in a future version?

We do tell you about it before we start recording any analytics.

You do now, after people noticed what you were doing. You didn't then, when the GA integration was originally snuck in.
