While I agree with his point about ecosystems (I strongly avoid them), these examples are a bit weak. Android is not an "open standard", it's a code-dumped open source touch OS controlled by 1 company. Evenmore, Android doesn't support standards very well. E.g., the default IMAP mail client didn't (probably still doesn't) have IDLE support, it doesn't have CardDAV/CalDAV support (luckily, there are external connectors), and XMPP federation is gone, so you can only talk with your Hangouts buddies via Hangouts. The 'problem' is that from a user's perspective Android is great. The integration with the Google ecosystem in Android is impressive. And given that many westeners already have GMail et al., Android provides a great and smooth out of the box experience. So, there is little reason to switch, as long as the ads don't become to intrusive.
