Sure, for those things.

However when it comes to web browsers, there’s been a looong history of failed attempts at selling commercial browsers.

I wouldn’t be at all surprised if the only people who’ve ever made any serious and sustained income from browsers have been Google; and even that’s been indirectly via upselling their other services.

This is what people said about Search before Kagi. And, incidentally, those folks are also working on a paid browser that real people do buy.

Times change. Subscriptions are normalized, and tech people are increasingly aware of the hazards of "free".

Content is something that is traditionally paid.

Not on YouTube.
