So far, we don’t consider this pricing option.
The price is very high. I read it use to be 6.99 a year now it is 6.99 a month. How many people are willing to pay that much for ssh? There are many many free clients available. I wouldn't mind paying something but not that much.
One time fee would be good for students and freelancers
Even though I don't use the premium features I gladly pay the yearly subscription to reward the developers and help ensure that enhancements and support continues.
I think the price is very reasonable.
I agree I find the price for the premium features a little high. I think a one time fee would be more reasonable then yearly.
