This is common knowledge for the marketers/analysts that I work with.
Have you ever run GA on a high traffic site or app?
Google gives you warnings. They're small at first, but when you're really hammering them and aren't paying for premium there are big red warnings about your data is getting heavily sampled. We have a relationship with Google, so they also personally reached out to us to ask us to fix the issue before they shut us off. I work at $BIGCORP so going through the procurement process is a lengthy process.
