This page should be ignored. The authors of the page clearly don't know what they are talking about. There are a few good suggestions in there, like using JSON instead of XML. However, the good is vastly outweighed by the bad.
Tk instead of Qt?
8c instead of GCC?
Sam instead of Vim?
It's contrarian for the sake of being contrarian. That in itself makes the page more harmful than many of the apparently harmful things listed.
