Yes, but the sale shouldn't end because I just said no. There should be room left for me to be delighted by the product, such that I convert into a paying user. Instead, I feel alienated and not at all interested in trying it in the future.
So which is it? Why are you alienated by a product that says "we're not for you" if you have no interest in being a paying customer?
I think it could be solved for stubborn people like me if the survey got to that point and said "okay, if you're sure, you can still click here to request access but after 14 days you won't be able to continue to use it without signing up. We think you'll be persuaded!" -- or whatnot.
Seems fair enough that people should be able to try the free trial without having to agree that they're theoretically willing to pay 20/mo
I agree that the "opt-out" is not great, but I would change it to just a warning "This is paid software, after the trial you will need to subscribe".
