What saddens me is that many people would just stop using Hibit if the author started to ask for payment as if he has an obligation to work for free. I repeat what I said before. I'll gladly pay for it if/when it becomes a paid product.
I totally agree, but I think with certain software, the sales do better when the asking price reflects the category of software.
I really enjoyed Total Uninstall back in the day, but the only feature it offers that this (and some others) don't, is the ability to monitor and export full installations to other windows installs, so paying as much as they are asking for the lighter versions doesn't make sense.
Another issue is licensing, something like an uninstaller is better suited as a life-time license, but only provided updates/support for a year, then extra charge for updates/support for another year, etc.
Also, I am only personally willing to pay for software that is actively developed. Even if the software does not require new features, it is nice to see the developer being active (such as in forums like these).
There are a lot of developers out there, that charge for products (such as Glasswire for example) with the
suggestive promise that development will be active and reasonable feature requests will be implemented, only to totally ignore the majority of good feature requests. Niche software deserves niche development.
Just my personal thoughts on the matter.
