1)Another Google drive/plus account begging. 2) data control/access. Same reason they don't include sd card slots on nexus. They can't mine/ad adds on offline data. And google code was too hard to monetize (old system and all) 3) inside Google, engineers get big raises when they make their pet projects work (see mayer and gmaps) and abandoned projects can be fiddled by anyone. So abandoned gcode gets abused at will by prodigal gdrive rising star. Much easier to sell you added users to a project being monetized than to justify you added monetization to a project the press doesn't mention anymore.
