That the point he is making does not apply to open source, but rather to freeware (which is open source too). Open source can be completely B2B, without releasing it to third parties. Also open source is not free software, so you can also forbid your costumers from sharing the source further.
EDIT: That's crap. I only thought about the aspect of continuing sharing, but if you also don't want your direct customers to know, then of course open source is very much relevant.
