You may feel it was a "great product" but apparently people were not willing to pay for your great product. Several companies and people get paid giving away their software.
I suspect that your DRM was so overly burdensome that it turned away any potential customers, you in effect screwed yourself.
If the DRM does not get in may way, or require me to do anything(i.e it is invisible to me) then I might buy that software, for example Steam Games, Spotify, etc have DRM that is invisible to the End User. I will grin and bear this level of DRM, begrudgingly. However if you go much beyond this no thank you.
If your software has Activation Keys, Installation Limits, Locks itself to my Motherboard that I change ever 6mos, or other crap like that then you would never get a single dollar from me.
