The comment I was replying to was about advanced devices in general, not specifically TSMC.
That said, MediaTek is not the greatest example here -- they're fabless, and most of what they design is fabbed by, you guessed it, TSMC. The better counter-example would be Samsung, who fabs at least some of their own chips.
