There is zero "secret sauce" in max for live.
Ableton and Max are totally separate codebases, and "Max for Live" is just a ~VST interface between them.
I do agree that "scriptable Ableton" would be far better for production and sound design than Max, because they make all the hard parts easy: MIDI, sequencing, mixing, etc.
In Max, you have to build everything from scratch, every time.
I think we're talking past each other.
I don't own Max for Live. If I want to use it, I either need to upgrade to Ableton Suite for $500 or I need to upgrade to Standard and buy Max for Live separately (also $500).
There's a huge ecosystem of tools that are implemented as Max for Live packages which I cannot access because I haven't paid the toll.
I see that even this new Extensions SDK is only available to people who have paid for the full Suite edition.
I'd describe that as a market opportunity.
