I think your are seeing things that are not there. As you could clearly see it wasn't a guide. It was just advice, and bad advice even.
I doubt the original statement was even from GP. But if you want to think it was that way, and think I'm fighting some sort of war against GP. Go ahead.
But that wasn't the reasoning behind removing the bad advice on the wiki.
And any strategy works in SP (example:

Now excuse me, I have a Disney war to fight!
