For ebooks in particular, owning what you buy isn’t that difficult though. You can legally buy DRM protected epubs in a lot of online book stores and then use the software calibre (open source) to strip the DRM. Much easier than with music, movies or software.
Yea. I like my MacBook and I like macOS (yes, I know, shame on me). But in a few years, when Apple eventually stops supporting it, I can just put Linux on it and keep using it (or give it to a relative who just needs a working computer). It’s good hardware and in true Apple fashion, it will probably outlast its software. I also have an old Core 2 Duo unibody macbook laying around and while it is possible to put the latest macOS on (thanks hackintosh community), Linux is a much better experience and the MacBook is sturdier and has a better trackpad and keyboard than most new laptops, even many that are much more expensive.
