From the initial post:

From his follow-up:

So either he doesn't think that Windows is written in C/C++, it's not "from Microsoft", or he doesn't know what "reading between the lines" means, because those literally are the words he said. Sure, he also said "and algorithms", but I'd argue that inferring that to be a significant difference would require a lot more reading between the lines.

I guess he could also quibble that "eliminating every line of C and C++ from Microsoft" was supposed to mean new lines of code being written rather than existing ones, but that's both not the way most people would read it (if I said I wanted to eliminate all water from the planet, most people wouldn't think I meant I was eliminating rain but leaving the oceans alone) and a bit dubious from a technical perspective (since leaving the existing Windows codebase intact would make it pretty hard not to at least occasionally need to write a new line of code in the existing language).
