I'd say it's also important to remember the types of projects that are easier to monetize. About a decade ago I wrote an OSS library that gained some nice traction, and it wasn't really monetizable (granted I didn't want that anyway).

Then there's companies that write open-source software and are not only successful in charging for it, but also have funding. I run Fossfox [0] that indexes companies that have either open-sourced their main products (eg ClickHouse) or that heavily contribute to open-source (eg OpenAI). The ones that open-source their main products: some of them do use copyleft licenses, but most surprisingly go with Apache 2.0 (and of course use some dual licenses; with "ee/" directories). The one thing a lot of them have in common is providing hosted versions of their software. A lot of customers don't want the hassle of running it themselves, and do pay for hosting and support.
