None of those are offering 5nm right now. There are only 7nm foundries out there, the article says they are perfecting their 5nm processes for commercialization, what means there are some months (maybe years) yet until we see them.

Also, Moore's Law is dead by years now. Not only process improvement became subexponential and much slower paced, but transistor density isn't growing much and the core of the Law that is cost/transistor has increased with the last 2 or 3 iterations, instead of going down.
