How influential something is has nothing to do with how good it is.

In context, it was a piece advocating against the use of GOTO to the exclusion of all other control structures (e.g, 'for' or 'while' loops, etc).
wyager's statement, involving PHP (for which there is not a famous "considered harmful" essay to the best of my knowledge, though there is "A Fractal of Bad Design") and goto statements, was a rather clear implication that both constructs are innately harmful in an attempt to counter n0us' assertion that influential/popular technologies imply a high quality. There was nothing said about using goto statements in presence of structured programming, but merely goto as an intrinsic badness. This is a common belief cargo culted by a many naive commentators and XKCD readers who do not realize that all control flow is derived from goto, and moreover that even in some languages with structured control flow it is still useful, e.g. for resource cleanup and breaking out of nested loops.
