@Moem et al.
Here's how I made the mistake.
It started when I sent this gag to a friend.

Friend showed me this, all Platforms (desktop, tablet, mobile.)

Note Android is taking a sharp fall, Unknown is rising, and the dominant Apple dataset is shown purple. Edit: No, it's grey! Just that the purple one stands out more.
Then I came back many hours later (well past my bedtime!) to look at Mobile OSes specifically.

Android falling at the same rate the underdog is rising. Blinded by expectation from the previous chart, I didn't realise that Apple had 'disappeared' from my perception.
Whoops.
