This is a great resource. I just think the term “landlord” is a misnomer here. It implies you’ll be making income off the rent of your new self-administered infra, and as has been pointed out already - mostly this site pertains to stuff built on hyperscaler platforms.
I’d probably say “…internet homeowners where, like in the UK leasehold property system, you’re still basically a tenant but without paying someone else’s mortgage, and even when you’re a freeholder the king actually still more or less owns the land”.
Admittedly this is less snappy.
