Probably the same path as any OS nowadays: using you OS as a commodity to support a distribution of software/HWs you lock away from users.

Non standardized poorly engineered/proprietary HW and poorly documented SoC makes it impossible for an OS to survive without the support of big companies.

FOSS massively benefits nowadays the worst actors on the HW/SW markets possible. If you wait long enough you will see the heroes turn into the villains. (cf The Watchmen).
