Infinity Engine Toolset / Open Source IE

I’m not sure the best place to ask, and I suspect it’s unlikely to ever happen, but I want to request that the Infinity Engine and associated Toolsets be released publicly and/or opensource.
I ask this because IE is the most underrated development kit for building ADnD adventures. It could be used to develop games based on other rulesets as well.
This is a plea for access to the engine. So many amazing products could be made with these tools.
