I've made it a happy habit of including Resharper in my list of tools that I use regularly and have come to rely on. I feel comfortable doing this knowing that if I have hard times ahead of me financially, that I at least have some hope of trying to earn an income by using the tools that I've already purchased licenses for. But with subscription based licensing I don't have that protection. I feel extremely uncomfortable making a gamble every year that I will be able to pay for access to the tools that I rely on for my subsitance and that of my family's. This is the exact reason I uninstalled other tool sets from my machine. I don't want my resources being held hostage in case I can't cough up a licensing fee once my current license expires. Please don't get rid of perpetual licenses.
