I am. Plenty of software companies give away software for free and make money on support, hosting, network effects, ads, etc.

But also, paying for software as an enterprise vs as a personal user are very different things. I don't get proper support, bugs and feature requests never get fixed, if a regression is introduced I'm just out of luck completely, etc. There's no SLAs.

If the software is open source I can at least fix issues myself for myself. If I'm paying for software I'm also paying for new bugs, lack of support, and constantly increasing prices. Somehow by paying money I end up with lower agency.
