While marketing should always be taken with caution, and I agree this slide doesn't tell much, why hating a company should disqualify the use of material they produce to explain the hate? Hate and distrust are not the same thing. I can trust that Google Terms of Service reflects partially what they do, and I hate them for it.
I had time to waste, so I watched the actual presentation the slide come from, and they admit they don't know where the transaction come from: https://youtu.be/dyyA0YjSslU?si=Cnm60dS_rA0q_Yd_&t=33m44s At the Q&A, they also admit they can't monitor transactions of other nodes, all they do is just try to know who is behind a node. It looks more like a compliance tool than a monitoring tool.
