I think the hard part is understanding if “finished” software is still maintained.

I’ll pick on AppZapper here. It doesn’t need to do much, it’s a Mac app that finds the files related to an application and deletes them, for a complete uninstall. It released in 2006, with v2 coming out in 2010. The website looks like it’s still from that era and the last update was in 2020, almost 6 years ago. To be fair, it’s a cool app, from the “delicious” design era. It makes a ray gun “zap” sound as it uninstalls an apps, for no reason other than to be fun. It’s great.

Is it still in active maintenance with nothing to do, and there have been no meaningful changes in how apps are installed in the last 6 years, or has it been abandoned? I really don’t know. If I’m a new user trying to decide if I should pay $20 for this app, what do I do?

I don’t want updates for updates sake, as that leads to enshitification, but there needs to be some sign that a user isn’t throwing money at a dead product. Or in the ls example, developing a workflow around a dead tool.

A ran into a similar question with Yojimbo. It also launched in 2006. When v2 came out it was a paid upgrade and seemed fairly minor for how much was being charged (at least to a broke college student). It felt like they didn’t really care about it. But here we are 20 years later and it still seems to be going. But it was 14 years between v2 and v3, and the last release was in 2023. With 14 years of support, maybe that v2 would have been a worthwhile upgrade for me in hindsight, but when they go years without an update, I start to question if I should be looking to something with more support. Should a new user buy and invest time in putting their data into something that hasn’t been updated in 3 years, or is that a red flag?

These are the things I struggle with.

What exactly is wrong with installing an abandoned product? Just because it's abandoned doesn't mean you can't use it.

Apple tends to expect a lot from its developers. Changing processor architectures is a big one. Unlike other platforms, Apple cuts support and moves on. If an app is abandoned, it starts to show sooner on Apple platforms than anywhere else.

If it’s something that will become critical to a user’s workflow, that can be a big problem. Why invest in an app without a future?

I think the reasonable fear is that the product no longer works. Maybe Apple changed a required API in 2021 and poster would be purchasing a lemon.
