You really don't get to complain about a proprietary format being retired due to age or even just disappearing off the face of the Earth. There's an astounding amount of software written for the sciences that uses proprietary binaries that are depreciated two years later. We all realized long ago that if you want to preserve something, export it as an 'open' or standardized format. That's why every image producing/editing software supports `tiff` encoding.
Your comparison is unhelpful. The expectations for broad-market consumer software and obscure narrow-market scientific software are entirely different.
Apple leads users to expect an easy experience, and not to need to worry about technical details. The cost of that strategy is that Apple should expect criticism when those expectations aren't met.
