> If a dev wants money for his work, he should license his work as appropriate and demand payments. If a dev releases his work free-as-in-libre and/or free-as-in-beer, they don't get to complain if the donations are "insufficient". The author might still do it (it's one of his options) but please note that proprietary core libraries (and proprietary software in general) are immensely less useful than open source software. The value proposition of core-js is that it's a basic piece of infrastructure that other open source projects build upon, and if it were proprietary, no OSS could depend on it.
