I don't see anyone saying the notch on a laptop is a "good" thing that they bought the laptop to get, just people who bought a laptop for other reasons justifying why an imperfect screen shape wasn't enough to make them regret the purchase. They're not being "milked" in any way I can see.
Compare phones, where manufacturers have actually created a narrative that camera cutouts are a desirable feature. Maybe people who bought new phones because they like the cutout design are getting milked twice.
I'm saving up to replace my personal intel MBP with a new one partially because using my work MBP I really appreciate that little bit of extra screen space. In regular use I hardly notice the notch, sometimes I'll even have fun watching my cursor jump back and forth when it gets close to one side of it.
