In my experience, often people just double tap the photos to like them on instagram. And since most people hardly used the button for liking, it was a prime real estate for shops to move into.

I think you're confused.

The "Likes" button on the tab bar wasn't to like a post. It was to basically see the list of all interactions on your posts or new followers/requests.

This hasn't rolled out to me yet (Canada). I'd be super annoyed about this.
