The comment has everything to do with editing content. Schmidt was effectively convicted on the content of his emails. I don't think Schmidt was able to edit an email used in that case.

It is a positive example of what the poster I responded to was claiming.

Additionally, this CEO (now of Alphabet) has continued to engage in seemingly illegal behavior over Google email. I'm not aware of Eric disputing any of these allegations, even though I have confronted him on them multiple times.
