Having followed Maciej for a couple of years, I seriously doubt he'd ever fall into the trap of feature creep. He's one of the most pragmatic software engineers, if not people, I've ever encountered.
The Russian and German sign-up page still reflects the old price. Story checks out! (Although I was slightly disappointed that it wasn't a fellow Slav discount.)
But with a name like "five nines software" customer expectations should be implicitly tempered ;)
