"Lasting" and "supported" are obviously different things. How much support do you get for a laptop from 2013/2014? I guess Linux stuff can still run, but I would imagine for most folks, there's going to be a practical limit re the software they want or need to run still working on hardware that old. Software will still run, but possibly not with newer security patches. And yep, with open source you can patch some of it yourself, but that market seems niche, and yes, that's not going to be Apple for your preferences.
