Hyperlink vs an actual button is not a good comparison. You don't have a mouse on iOS to hover over things to see if they're 'touchable' or not. Bad design is still bad design even if the cool kids are doing it.

You should note that on the web many have abandoned the hyperlink for graphics that represent buttons: http://getbootstrap.com/getting-started/#examples

There's no mouse to use to hover on mobile or tablet devices on the web, either. I haven't seen any push for change in how hyperlinks work on the web now that mobile/tablet is a common client.

Stretching the concept a little here, but design that hinges on being able to hover the mouse to detect possible interaction reminds me of those dreadful 90's web menus where you had to hover to see the title.

In your linked example, there are as many or more hyperlinks that don't appear as buttons. The button styling in those examples indicates "primary call to action" more than anything. A page that uses button styling for every single hyperlink would be a mess. The iOS 7 styling for "primary call to action" is to make the tinted text bold, rather than giving it a background color, though that's used in some different areas too under different context.

PS, a side note that these are 3rd party examples of iOS 7 UI. Certain things are going to be misused or overused etc.

No one suggested buttons where links suffice.

On the otherhand, if you think a bolded link is a good replacement for an action button like "submit", lets agree to disagree.

Not claiming one is better than the other, just pointing out how semantics have changed with this new model.
