I'm well aware of what you wrote, and I'm well aware of the section you are citing. Their method of measuring copyright infringement is very sketchy. They can only measure public links, so they miss the majority of the data stored. I don't trust their algorithm either, given the ridiculous amount of false positives in automated DMCA requests. They don't give their results for non-"copylockers" like Dropbox. Mega claims in their blog post that 99.7% of the files they are hosting are smaller than 20 MB. That almost all of those are copyright infringing is not plausible.
