When I pay for some physical product it is MINE. If you put something fancy in there, you sold it to me, IT is MINE. I can't copy it and sell the copies, that's fine.
If it's a truly great product, I won't have to fix it. If it wasn't as good as you could make it, you've cheated me. If I can't fix it then you've cheated me in an attempt to keep not just the product but me tethered to your stockholders. Sad.
Sad for you. If it's worth fixing, and you expect to bleed me to fix it, I can fix it myself, or find someone who can. That's a LOT easier than before. And you've lost another customer for a lifetime, one who will spread the word at every chance.
