> Your saying that this being a possibility means all proprietary software is immoral is like saying that since some businesses are pyramid schemes, all businesses are immoral.

No, I'm not saying that. I'm saying that proprietary software is immoral because it takes away an important human freedom - the freedom to control our own computation. You're said "ok but what if someone agrees to use proprietary software?" then I said "that does not make proprietary software any less bad".
