How do websites without ads make money?

Question

Monetization

What do sites earn without advertising, links to donations, miners and other husks?

Answer 1

There are many sites that don't make money at all. This is fine.
There are sites that are supported by an implicit sponsor. For example, Wikipedia lived like this for many years, and donat appeared relatively recently.
There are sites that belong to a certain project that brings in money. And the site itself is just a makeweight.

Answer 2

A site without advertising will not last long, and it probably doesn’t make sense, but if this is a site of some large owner, then most likely the strategy is aimed at luring the audience for monetization in the future
