I'm always taken aback by the hostility toward clicker training; I am unaware of any clicker trainers kicking in doors and forcing their methods on others. :)
Dogs ability to focus on the trainer, and the clicker of the moment, is a simple fact, easily observable.
A training method that is both fun and effective has much to recommend it, and I've never seen a better method with puppies. It is work for the trainer, one of the hardest things is to learn to be quiet, and truly study and learn from the dog. Clicker training is very much an interactive process.
I think some people who are so appalled by clicker training of course haven't seen it, but beyond that imagine there is no proofing or corrections. That's quite a false picture. Clicker trained dogs even compete in dog sports, right next to the dogs trained with other methods.:)
