Very relevant is this old post by Joel Spolsky on tech companies using free and open source software to commoditize their complements. https://www.joelonsoftware.com/2002/06/12/strategy-letter-v/

Basically, you can increase the demand for a product by decreasing the cost of it's complements. You can increase the demand for managed Redis services by investing in making Redis better. The caveat is that you can't control where that demand goes and you might end up helping out your competitors more than yourself.
