The Free Software Definition mentions "user" 22 times and "freedom" 79 times, whereas the Open Source Definition has zero occurrences of these terms. It doesn't seem surprising that the user freedom message isn't getting through if you completely scrub it from the messaging.
SaaS is the least free model for software. You have no privacy, no control, and in most cases can’t even export your data.
Thus open source actually minimizes freedom in practice, at least for everyone other than developers.
