If you actually use and care about the software this shouldn't be an issue. Unfortunately to run even a small business where a niche product only needs to be bought once it needs to be way more expensive than that licence was.
I have a lifetime licence to my text editor and I've used it every day for over 10 years, wouldn't have an issue if the creator changed their mind about it and actually the community has asked them to so it could be supported but they were not interested.
