The question seems to be whether it is allowed to create what is effectively a competitor framework (on your own volition and without authorization from your employer, as in the case of MVIKotlin vs MVICore) under your own name (brand), potentially in your free time, but based on designs of an open-source framework managed/developed/maintained by your employer in employees' time. And even if it is allowed, can your employer claim ownership on the basis that your work is derived from employer/company work. However, I think this is unprecedented (I can't think of any similar cases regarding reclamation of IP), and we'd have to be actual lawyers to know the answer. I'm curious to see where this case will go.
