It's not open source. Many people find it easier (or think it's easier) to generate a revenue stream from selling closed source software than from selling open source software, so they decide to make their software closed source. We need to gatekeep terms for them to retain their meaning. We can't just accept it when tech companies try to change the meaning of "open source" to mean "we published the source code so you can read it". The term source-available exists, and it means something different from open source. If these people announced that they're making their software source-available, everyone would be happy, but they're not.
