Precise motives? I don’t know, I don’t think I have any. I don’t use starlink myself or have a Tesla or invest in any of his companies. Feels silly to disclaim that, but there you go.
Having used starlink before on a plane and on land, it’s fast and seems far superior to previous generations of satellite internet. I’m earnestly asking if creating problems for astronomers is outweighed by giving more people access to the internet. Not just giving them “access”, but giving them very fast and low latency access.
