In a general way, I'd say that there is a moral, if not a legal, question about the supplier of free stuff. But let us distinguish.
(1) If someone gives me a free toaster, and tells me what an awesome toaster it is, and how I don't need to
buy a toaster 'cos they're giving me one for free, and then it breaks, then I'm just back to square one. I had no toaster, briefly I had a toaster, now I have no toaster again. I can always resolve this problem by buying another toaster.
(2) If, on the other hand, someone gives me a free parachute, and tells me what an awesome parachute it is, and how I don't need to
buy a parachute 'cos they're giving me one for free, and then it breaks, then I am
not just back at square one. I'm plummeting to my death. And I cannot resolve this problem by buying another parachute.
Now it seems to me that if my free email stops working, this is more like the second case than the first. I am not just back to square one, and I can't resolve this problem just by buying another email service.
