That absolutely isn't true as a blanket statement. It varies a lot in terms of B2B vs B2C, distribution model, etc.

With B2B software using the popular model of "paid hosted SaaS + libre self-host", you can definitely get revenue from companies who happen to employ some open source purists. Ditto with the model of "libre self-host with paid technical support". But all of this is much harder with a non-OSI license, since the open source purists will protest, regardless of whether or not the company is even running the self-host version.

Software adoption also tends to follow network effects, so having any contingent of vocal people complaining about license choice is bad news for a business.
