Actually, they aren't in beta anymore with it being on the Play store so I guess that was their criteria for being in it for so long.

It was a big deal when SwiftKey and Android 4.2 implemented its own version of "Swype" and both promoted it. I've used all three KBs and prefer Swype because it's the most accurate for me.
Not being available in Play store doesn't mean you can't get it. You just go to their website, sign for the beta, then you download the apk. ANYONE could do this.
He's talking about a style of play. Generally, "macro" play is going to for the long-game with many bases and huge armies. He calls the opposite of this as "rush." Other synonyms for "rush" are something like "timing attack" or "all-in."
