What happened?

Is there a post somewhere that explains in simple turns what has happened here? Or, can someone give a quick rundown?

I get that there was some kind of butout by Tron's Justin Sun, and there's a hardfork, but what is what?

Steemconnect and Busy are now really HiveConnect and Busy.org is on Hive?

Because this confused the hell out of me:

I've been reading about the drama, and it's got me very curious is all!

P.S. Haven't been around much at all tbh. But maybe that'll change... :-)
