this is a Just World fallacy, assuming the best thing will always be adopted and therefore everything not adopted is worse than [current thing], when it is entirely possible that there are in fact better options

I didn’t say there were better options. I didn’t say it shouldn’t have been adopted. I said it has some drawbacks, wasn’t rolled out very well, and I miss having other options even if they aren’t as generally useful for everyone, and it is inevitable that some people would complain because of that. That isn’t a problem. It’s okay to complain sometimes. We all do it.
