Earlier quoted context omitted.
You're commenting on a post where a random guy provides this "nightmare of supplying and supporting an app" in his spare time, except he actually has to work around Apple's malicious obfuscation and standards non-compliance, so it would actually be way easier for Apple to do it themselves.
It is in fact significantly harder for Apple. Because nobody expects random spare time GitHub project to work perfectly. Or even very well. Apple’s reputation, and trillion dollar market value, is based on the idea that their stuff works perfectly.
Ugh, trillion dollar market value doesn't mean they are incapable of making a basic android app. Check their move to ios app if you have any doubts.
