Others (including many in the media) have an anti-oil agenda. So you may not have heard as much about this phenomenon as you should have
Some of these phenomena are also unheard of because they simply exist as part of a pro-oil agenda, not serious science. But this article seems rather serious.

Unlike in Google's case, where Chrome is based on an open-source browser named Chromium and where everyone gets a voice, everything at Apple is a walled garden, with strict rules
So why is Chrome not a walled garden?
Apple's OSes also don't properly handle the Matroska container by default. Matroska is used a lot in modern multimedia (including a limited subset of the Matroska container used for years in WebM). I think that Apple's choices help render Apple's OSes as also-rans and I wouldn't be surprised if this is based in Apple's preference for patent-encumbered stuff to which Apple is a licensee or beneficiary.
You are right: MP4, also called ISO Base Media File Format, is an ISO/IEC standard. Its patents can thus be licensed under fair, reasonable, and non-discriminatory terms (FRAND) from its inventors
The reason why they won't adopt competing technologies (matroska) is because of the effort they put in developing the QuickTime File Format (.mov) and then getting it standardised as MP4.
