You mean one with a business model where the user isn't the product? I happily paid for a (fairly expensive) lifetime license of Niagara, hoping that I will never read an "after the acquisition, all developers were fired and all ad frameworks were added" article about it.
I bought the lifetime license, but I guess I bought it before they raised the prices. Unfortunately, I feel like it's too much of a niche product to be sustainable on the previous price they had.
$40 is a lot of money for most people, but probably not for a big portion of the user base here. (but today, I too would probably not pay that much)
