Closely followed by Samsung-sluts to retaliate with spin.
If you believe this article, TSMC is doing better than Samsung.
Rumors in the industry support the idea that TSMC is doing very very well with 20nm and 14 nm. People shouldn't judge the company on issues they may of had with one process, the reality is TSMC runs many processes, problems are bound to crop up form time to time.
Besides one of the digs against TSMC is the quality of the GPU's that ship from Nvidia and AMD. TSMC shouldn't be blamed for bad design and running the chips to damn hot. If you are wondering why Apple ships the Mac Pro with the GPU's running slightly slower, it probably has a lot to do with trying to achieve acceptable reliability.
