I - and us Packbats collectively - think it's a good thing when stuff that works is kept out of the trash. That's not a terribly controversial statement, I think.
Unless you're Microsoft. Our newest computer is ten years old and they think it belongs in a landfill - even Windows 10, the OS they don't sell any more and will stop supporting next year, doesn't support it. To Microsoft, our ability to have a computer at all is only permitted if we pay to give them permission to install their latest ad service and maybe also their latest AI spyware.
Or you're Apple, and you secretly push updates that shorten the battery life of old iPhones - an update which many believe was deliberate sabotage to force updates. After all, Apple has a deliberate policy of shredding old phones rather than allowing them to be repaired, which removes the option of buying used rather than new. This is also personal for us - our iPhone 6 was working perfectly fine, and then it started overheating and running dry faster and faster.
They can do this because their software is proprietary, and their hardware is proprietary, and their customers have no choice. It's put up with the abuse or run a zombie operating system for eight years as you watch more and more of the modern world cease to support your computer.
FLOSS software isn't like that.
And yeah, there's more to it than that. It's more complicated than that. There's an entire universe of philosophical, pragmatic, and political calculation going on, conversations about rights and safety and governance structures. But our 2010 laptop, a truly delightful and fast machine to live in running Windows 7, is ... still that, running Xfce in openSUSE. Because to Unix, an Intel Core i5-520M is just another amd64-compatible CPU, and 4 GB of RAM is more than enough to run a graphical desktop environment - y'know, the thing with windows and mouse and taskbar and so on, where you can double-click a PNG file to see it pop up in an image viewer. Why would it be inadequate? They aren't selling us dissatisfaction or new shinies - they're making things work, as best as they can, in a world that doesn't want your computer or ours to survive.
Everything that's annoying about FLOSS software is because FLOSS is a world where something made mostly by 11 developers with an annual budget of under US$8000 is basic infrastructure for literally millions of users. And that's not even strange here - like, there's standards designed for interoperability, and those get created and implemented by a crowd of different projects. Instead of Microsoft designing Word documents in secret to ensure no-one else's programs can open them, you have LibreOffice using the Open Document Format that anyone else, from megacorps like Google to some random single dev making a project solo, can implement. It's just how things happen here, and it means that one person can make a project for millions that mostly works.
Even when Microsoft and Apple would rather you pay for their thing. And be locked in their house. Where they can force you to give them more money.
There's more to FLOSS than that, but there doesn't have to be more to FLOSS than that for us to care. Our computer is alive. We can't not be passionate about that.
