This is a kind of nuts take; - Senior engineer - Uses tools for non trivial undertaking - Didn't find value in it

Your conclusion from that is "but they are doing it wrong", while also claiming they are saying things they didn't say (0 net benefits, useless, etc).

Do you see how that might undermine your point? That you feel they haven't take the time to understand the tools, but you didn't actually read what what wrote?
