I do try to avoid installing app updates on older devices. But sometimes I’m forced to, like when WhatsApp introduced audio calls. It works on my old iPhone 4 though video calls don’t.
I don’t think Apple should stop innovating. Just approach innovation differently. Thanks to your comment, I realized my original post wasn’t clear about this so I edited and appended the bit below to it.
So is there a solution?
I think Elon Musk of Tesla has one. He seems to have figured out this kind of forced buying is alienating loyal customers, beside adding to the huge environmental pollution. So Tesla started fitting its cars with new future-proof hardware that can be updated with newer software. This means an old Tesla car will have the same software and features as a brand new one!
I think that model should be a benchmark for the tech industry.
