No, you almost certainly promised not to do so when you bought a licence.

Ghidra on the other hand you could, since even if they never get around to fully releasing the source (unlikely) they still granted us an apache license on the whole thing :) I think it's probably pretty unique right now in that it's under an OSS license without all the source available.

  Ghidra is mostly Java, so decompilation would pretty high-fidelity to begin with.

    The java sources seem to all be there in zip files actually (as far as I can tell). The part I was most interested in atm (the decompiler) turns out to be some sort of native language compiled to an executable, and its source isn't there.

  All the source is in .zip files in the download. What's missing (and coming soon) is a build system.

That’s actually untrue - they explicitly give permission to reverse engineer their software in the license. Check restrictions in https://docs.binary.ninja/about/license/index.html https://docs.binary.ninja/about/license/index.html
