Although I agree with your overall point, there is a middle ground here: (commercially) non-free but open source software.
I believe that's where the biggest disagreement ITT lies. There are currently good ways to do FOSS, proprietary closed-source and free closed-source software development. But if the OSS is worth charging for (commercial) use, devs are left with asking for donations, SaaS or "pay me to work on this issue/feature".
There arguably should be better mechanisms to reward OSS development, even if the largest part of an OSSndev's motivation is intrinsic.
I'm sorry, but in my mind, open source and commercial don't mix. What would a license for that even look like?
I'm not saying going commercial is bad, go for it. I'm just saying that when we are talking open source, we are not talking money, that's all. Money is just one of many things in life, sure it's important, but not by itself.
