The guy who posted the story of splicing a 500kW cable wasn't looking for money. He wanted to amuse people and thanks to him we got amused endlessly. The costs of putting things online are $5 per month at Digital Ocean.
Plus the knowledge you can, and non-trivial technical expertise like: registering a domain, DNS configuration, setting up web software (even if "one click"), and maintaining it over time.
Do you have a link to this? I've tried googling "splicing a 500kW cable" (and variants) and haven't found much relevant.
