Obviously you're being sarcastic, but they're not just dumping netgear routers on walls and saying "TADA! MESH!"... They're actually using industrial grade equipment to do this.
I missed the "industrial grade equipment" part in the arcticle, TBH. In fact I saw no real technical details at all. "Mesh" isn't even really defined. You'd think they'd at least mention what firmware they're running on their gear to implement "Mesh".
