Yet i don't see that happening, what public funding does Apple product has really depended on ?

R&D is only part of taking a product to users. There is a lot of steps in between , marketing , support , distribution , manufacturing, packaging a new tech into viable a value proposition and so on.

Research is important , but purely research or even better tech alone is insufficient, there are plenty of examples of companies who have great R&D but failed to make useful products used by real people at scale (aka commericalize) .
