While starlink is a relatively cheap alternative to other satellite providers, and at one point provided a better experience, both the price value and experience has continued to degrade over time. It would be a great UN-provided project. Genuinely we should have a similar system (better engineered and designed) available to be used by anyone at cost. But SpaceX is a public company, it's only going to continue to enshittify and will eventually become a worse value consideration than alternative satellite providers; it's already enshittified with many customers reporting consistently double the ping and half the download speeds from their original experience.
It's not the idea of a truly globally accessible internet that makes it worthless, it is the fact it is being done by a for-profit publicly-traded company owned by a trillionaire. Any one of those three things would mean the product is guaranteed to get worse eventually, all three mean it is guaranteed to get worse as quickly as possible.
