A compiled executable is not any less software than the source code. But the point of open source code is not the ability to see the CPU instructions though, is it?

Its about reproducibility and modifiability. Compiled executables (and their licences) lack that. The same as these downloadable blobs.

Is this question in good faith? The way generated code and data should be open sourced is by releasing the tools and configuration used to generate it. There's never been much confusion around this, to my knowledge.

I'm not even necessarily advocating that these things should be released, but the term "open source" has a pretty well-understood meaning that is being equivocated here.
