Regulatory Product Roadmaps

I wonder how you push back easily against tech giants that try to say their technical systems are too tethered to be separated. Could congress require a technical roadmap for separation of concerns and detached systems? I think so. The product roadmap could be disclosed to a private working group and impartial developers and product designers could with a few sessions evaluate the feasibility and satisfaction of the implementation. Slowness to implement could yield significant penalties.
