There's absolutely things wrong with proprietary software. It leaves software users in the position of having technology that they cannot control freely. See, e.g. the arguments from GM and John Deere that you do not have permission to modify your own car or tractor. Or countless other examples. And basically zero of the people who pay for proprietary software are saying "I'm so glad this is proprietary". They pay because the package of what they get in utility is worthwhile and outweighs any concern about the proprietary nature of the software.
