I don't think this was actually established. The author may have a point about the UX of multiple cursors in Sublime, but comparing that to Vim macros is missing the point of the macro system — i.e. that you can create something that persists between editing sessions, and encapsulate a sequence of steps even of fundamentally different kinds. (For example, do multiple cursors allow you to implement a new command to transpose elements of a comma-separated list?) More importantly, though, this is not addressing the general principle about "extra features".
I haven't known other Vim users to speak of such "games".
