Yes, he absolutely does hate Noodler’s. I have a friend that has been into fountain pens for a long time. He recommended to go with Noodler’s since so many have archival and waterproof properties. Other inks were referred to as expensive food coloring.
If you are writing notes that won’t matter in a few months then a dye based ink is just fine. If you’re writing something that you still want read in 50 years then you want something more permanent than a dye based ink. Each case is fine, but the author is definitely pushing an agenda rather than providing a holistic view.
