A lot of this is not deliberate. It's just incompetence. Writing good product descriptions for a website is really hard.

How do I know? I write copy for our website. Even though I'm an engineer it still tends to come out as fluff + engineering word salad. It takes multiple iterations to get it right. I have huge respect for people who can do this well.
