Well, the article makes the point that Starlink is definitely not under anything close to what it’s expected “peak load” will be, and even so, it’s not currently meeting speed requirements.
But mostly, I agree — the article seems a little over-worried.
I didn't know why people are getting bad speeds, because I'm regularly exceeding these speeds on my dish. Starlink requires self-installation and I'm willing to bet that a lot of people don't understand how to set it up properly. I will say it took me over 2 weeks to really get a good location, top some trees and set up a proper mount above the house. People post pictures of their dishes just sitting on the ground, and a lot of people don't have patience or time to get the connection working well.
