IMO you’ve been unfairly downvoted, as you’re correct that the emoji illustrations indeed are owned by Apple.
The fault lies with the Unicode consortium for opening this can of worms. The standard should have been reserved for outline letter forms only. Adding a set of full-color illustrations that expands every year was madness.
It’s especially bad for embedded devices that need to render text. It used to be that you could ship vector fonts for the major global scripts in less than 500k, and you could feel fairly confident that new glyphs aren’t randomly added.
Today you need to ship an emoji font and make sure that your font engine can render color graphics. Google offers the only semi-decent free color emoji font, and it weighs about 7 MB. That’s a vexing increase in system font footprint just so that there’s a poop illustration on disk when needed. You also need to update the set every year when the standard adds “depressed poop” or “sulking lizardman” or whatever.
From a UX point of view, it sucks because the free emoji font doesn’t look like the Apple one (because that look is copyrighted!), and inevitably someone will complain about it.
At least HN has the good sense to filter the emoji junk from
comments.
