Great story, thanks for sharing. RIP John.
I kind of miss the age of freeware and shareware. It was often created by passionate individuals who put in a lot of care into the end product, which made it a joy to use. Once you paid for the software, you not only got the full version, but you felt good supporting someone who genuinely deserves it. There are still some examples of this, perhaps more so in the Apple ecosystem where proprietary/commercial software is the norm, but high quality software worth paying for is still rare.
Nowadays most software on Linux is open source, which is great, but the average quality is low, a lot of it is produced with little care and effort, it's quickly abandoned, and now in the age of "AI", even more so.
