You obviously don't know what you are talking about.  Did you even read the link you posted as 'proof'?  TSMC is a foundry and accepts orders to use their foundry.  Apple is even considering using TSMC for their A7 processor:

Lots of big companies are fabless (such as Apple).  Xilinx & Altera have even made their FPGAs at TSMC in the past.  Although I've lost track where the Virtex7 is made now:

Anyone can buy foundry time.  You can even run small MPW lots using MOSIS.
