That sort of coincides with TSMC having competitive, close to leading edge nodes (so the 28nm timeframe) which would line up with the rumor. The information simply hasn't been updated over the timeframe of the node. Previous to that the cost of the node was pretty fixed as long as someone like ARM cared about, now there's a lot more economic effects from the increased buyer competition that heavily changes final cost over time.
At the same time, AFAIK Intel was doing quite well at 14nm finfet even then (likely better than any other foundry?), but that production capacity was not available to ARM, so I guess it didn't count.

Yeah, and Intel was right in the middle of their biggest misstep. Intel 10nm was in risk production for Cannon Lake with awful yields and therefore a huge $/transistor. It got shipped anyway as one SKU in May of 2018 that didn't make financial sense (there's rumors that management bonuses were tied to that release), before being relegated to process improvements for years until just recently.
It would have been fair for her to extrapolate a trend there that actually ended up being more complex in hindsight.
The data has been saying otherwise. 5nm is the only node that increased $/transistor beyond it's previous node (7nm), and that's at a time when Apple payed out the ass for a monopoly on the node except testing shuttle runs from competitors but isn't a sign of a fundamental increase in cost.

> and that a 7nm die cannot run more than half of its transistors at the same time without melting.
That's true for trying to run multiGhz designs in classic plastic package BGAs like most cell phone chips, but that's been true for a while, hence why flip chip packages are a thing. Actually having a heat spreader connected to the die goes a long way.
Wilson's comments aren't incorrect from a certain point of view, but tend to get extrapolated out of her niche to the greater industry in a way that pushes the statements into inaccuracy.
