If a company X doesn't want to support something, then they should open it (source code, hardware specs, ...) so someone else can continue to support it. Always having to trash something that is working fine is stupid. For example, I have an old iPad2 (last Apple device I bought) that is working perfectly (the hardware). But I'm not able to install anything "new" on it because iOS 9 is no more supported by applications. Why Apple doesn't open specifications so i can install Linux on it to extends its life for many years to come? I take an example from Apple but it's applicable to ANY companies.
