I do not remember anyone saying Starlink would fail.
I really really despite Elon Musk for plenty of things but i don't think Space-X is not successful, i just think its not worth its share price.
But i'm for sure not liking that one person can just decide to put stuff into our space and disrupt research and my view without paying for it somehow.
And the biggest issue ish Elon Musks behaviour: he is for sure no one who would take something like atmospheric poisening serious until its too late or someone forced him to do so.
