Lisp survives in part because of Emacs and MIT. Oberon never had an equivalent application.
Wirth-ian languages is about languages as engineering. They're precise and pragmatic - e.g. constructs were stripped out if Wirth did not feel he could translate them into assembly in a compact and simple and easily understandable manner; he put restrictions on adding improvements to the compiler that didn't "pay for themselves" etc. The entire toolchains and systems and languages he worked on is focused on this.
