How Much for an Add-On? (Patreon)

Hey Squad, I would like your opinion-! (definitely leave a comment if you got the time to flush out your take) - In the next vid we're going to be talking about a subject that I feel is extremely under-explored. I had a good discussion with some other software users, and they pointed out something of a paradox within Blender that I do think is worth giving thought, and that is, at what point does a paid add-on defeat the point of Blender being free? - The best retopo addons are well over $100 bucks, the best facial MoCap shape key addon is $100, auto rig pro is like $40, and there are many other paid addons for other things like modeling, and UV editing, that when you total up all the prices, you're more than half way to just purchasing the pro software like substance or zBrush for the permanent license. The irony being even if Blender is free, all the best add-ons for it are usually paid. So, I wanted to ask, if you knew an add-on would increase your productivity by 5x. How much would you be willing to pay for it?
