Depends what you mean by "founders." You can certainly enable people who have interesting ideas for worthwhile projects without enabling them turning into owners of megacorps, and I think he's playing on the confusion. Google the search engine started as a Stanford research project, and we should, as a society (I'm intentionally not saying as government) provide additional support for grad students who want to develop cool projects and make them real who aren't interested in turning into business owners. Saying "Don't start Alphabet Inc." and "Don't start Google the search engine" are very different things.
