I don't think the writer of this article has thought this all the way through. Sure, replacing one of the SAASes from your tech stack with some self-hosted OSS will reduce your spending (as long as you spend less on the operations than you did on the SAAS of course). The main problem for tech companies comes when all their customers have the same idea and cancel their account in favor of OSS alternatives. That would lead to a much deeper downturn.
I also wonder how the "use FOSS, it's free!" mindset will coexist with the "pay OSS devs more" movement. That will be very interesting to watch for sure.
