TSMC presents "targets" at the symposiums not specs based on production chips. Until the PDK is 1.0 (production) you can only talk targets unless you have test chip data which requires an NDA. And test chip data only tells part of the story. Production chips like the A11 tell the complete TSMC 10nm story and it is a good one, absolutely.
If you want to look at the process level specs read Scott Jones because he is the gold standard:

What you will find is that TSMC 7nm is comparable to GF 7nm and Intel 10nm. Last I heard TSMC 7nm will be in production in 1H 2018 and Intel 10nm and GF 7nm in 2H 2018.
About your sources: TMFChipFool has zero semiconductor experience. Ian Cutress zero semiconductor experience. Charlie Demerjian spent some time at Intel many many years ago but has zero foundry experience. And here is my problem with Rick Merrit: He is supposed to be a professional journalist. I have seen him take and publish pictures at events that clearly state no photos. He also blurs the line between fact and opinion with personal bias. So yes I am saying the mainstream media routinely spreads misinformation which should not surprise you.
