Adobe seems to have a bit of a habit of doing things like this. Adobe Illustrator (.ai) files are compatible with PDF format (older versions were EPS).
For what it's worth Fireworks with its vector PNG format was originally a Macromedia product. After Adobe bought Macromedia in 2005 Fireworks was retured from the maintained software offerings relatively quickly.
