> "Am I using the correct language runtime distribution (or version thereof) so I don't get into legal trouble?" Is a question none of Java's competitors have to ask.

I am not sure this is 100% true. I think that if you download a specific binary of Anaconda (for Python), you may get into a situation where you have to pay.

For example, at Anaconda.com, one can download their distribution (their build) but the fine print says: "Use of Anaconda’s offerings at an organization of more than 200 employees/contractors requires a paid business license unless your organization is eligible for discounted or free use."

I think that PSF License is permissive and allows binary versions of Python without the maker having to release the source code.

So, downloading Anaconda as a Python distribution (build) is analogous to downloading Oracle JDK (a commercial build of OpenJDK, from Oracle).
