While at first glance it would be strange to expect Apple to make these changes; I don't feel its unreasonable from any perspective. Apple should hold a long-term interest in keeping the web diverse; Safari will never reasonably hold a majority/plurality marketshare, so their second highest priority from a revenue/ux perspective should be "sticking to the standards" and helping toward ensuring web developers don't take on a "Chrome and nothing else" stance.
Granted, its also understandable that Apple officially working on Firefox would be "article on The Verge" level of news and even an armchair commentator would be able to connect the dots from what they're working on to predicting Facetime was coming to web. Though, isn't that what Jobs originally promised? Open source protocol and such?
At the end of the day, I'm sick and tired of the prevailing hyper-endstage-capitalist excuse of "they won't make a billion dollars from doing this, so not only will they not do it, but they SHOULDN'T". Its everywhere on HN, and its actual brain worms. Corporate decisions shouldn't only be analyzed through this lens; there's a far broader humanistic lens that codifies a higher standard that we absolutely can reasonably hold all companies to; not from a legal sense (HackerNews isn't a court and your votes are not a jury decision, some armchair commentators need to be reminded), not even from a general population public relations sense; but from a viewpoint that Ethics is not a democracy, there are some ethical positions that won't make money, aren't required by law, and aren't even popular, but are nonetheless crucially important to avoiding a Blade Runner-eque corpo-cyberpunk future (or, with some very legitimate issues, species extinction or at least achieving and maintaining a high standard of living for most of our species).
The sibling argument of Firefox's CEO making a ton of money being reprehensible is... I mean, jeeze, they make awesome software, open source, freedom respecting, privacy respecting, and manage to pay their leadership & employees well? Isn't that the dream? That should be the goal; not be derided. There's a middleground between hyper-endstage-brain-worm-capitalism and "all software is developed by starving monks in a monastery". I understand its hard to believe this, because it isn't an extreme; its easy to let gravity drag your ethical viewpoint to an extreme on the left or right in this age of outrageous social media, but neither extreme on any ethical dimension is conductive to a positive future for humanity.
