While I agree with your broader sentiment about this post being more change aversion than substantive debate the logic here is circular: if "multi-bazillion" dollar companies always initiate change because they "have the data that tells [them] it's going to make [them] more money" then any decision by a large company is self-evidently correct. This is false; the large company could have overlooked things, made a logical error, or have had an idiot on the web server team pushing changes he didn't realise broke iOS's WiFi capabilities. Your argument should push deeper than an appeal to Apple's authority.
