Why didn't Twitter leapfrog Facebook in the Like-wars?

I wonder why Twitter didn't leapfrog Facebook and offer an array of different Like-like emoji. Facebook has said they're going there. Twitter would have no installed base expectations to overcome, and they could have been backward compatible if Favorite was one of the options (with star as its icon of course). They could have made heart the default.
