Doesn't mean he wasn't right.
iOS is majority in a handful of countries, mostly small very rich countries (Monaco, Norway, Denmark), North America and Japan (probably Australia too by a smallmargin) and North Korea.
In UK to situation is 53% Android, 46% iOS, which is kinda strange for UK, the country of London, the temple of global finance. Being majority in UK is like having 80% of the market in Germany.
> Based on app metrics, iPhone users are more likely to use their device.
that's some spurious correlation there!
of course app metrics say that, Android users can use a web app! They aren't trained to only use whatever Apple wants them to use.
