After the original developer and owner of waze sold it to google I don't remember when but was asked about the sale, etc. He said that it was the worst mistake to sell to google and let them get ahold of Waze. But I guess money talked at that time. Would imagine google paid a handsome amount to buy up the top competitor.Still totally different products thankfully. Google hasn't butchered it.......yet. (FTC started looking into it again, but haven't heard anything of the new investigation in a year now.)
Google maps sucks. Waze is about the only "google product" that doesn't suck. (android has it's problems but isn't their worst product.
In order to have anything decent, they had little choice but to buy a superior product. It's how fakebook and google both survive - buy the competition.
So yeah, they must have agreed Google maps sucked, so they had to find something better.
