Counter-arguments:

His energy pool is not bottomless. Without proper management in skrimishes or team fights you will run out, making you a sitting duck until it replenishes.

He can harass like a boss, but he's also very squishy early game. There are a number of difficult matchups for him (e.g., Katarina, Leblanc, Veigar, etc.).

Building attack speed is wasted on AP Kennen because AP items are way more powerful. If you build him AD, well, good luck trading with Caitlyn, Kog'Maw, or Tristana. He can, however, last-hit pretty well, but so can any ranged champion.

Kennen usually plays mid, which is the easiest lane to escape ganks from to begin with. Sure he's hard to gank, but so is Vlad, Caitlyn, Riven, Leblanc, Swain, Nidalee, Corki, Tristana, etc. etc. etc.

His ultimate is amazing for team fights. However, it requires two major things: coordination and scaling. Popping off your ult is not a guaranteed win for your team (e.g., they have Janna/Alistar/Tristana/Lee Sin, you time it badly, or your team doesn't take advantage of it). Also, it's not that amazing if you're underfarmed. Kennen snowballs/scales very well, but if he's underfed, it just won't be as painful as you'd like it to be.

"He's just so good at EVERYTHING." You basically nailed it here. He's not really the best at any one thing, but he's good at everything.

Kennen is easy to counter if you grab a Cho top and Alistar bot. Have fun doing much of anything in team fights vs. that kind of CC as Kennen. Oh, and have you ever tried exhausting him in team fights? That sure poo poos on his damage.

And for reference, successive stuns have diminishing returns.
