I agree with you, but I'm completely aware that the point you're making is the same point that's causing the problem.

"Stuck in a rut" is a matter of perspective. A good marketer can make even the most established best practice be perceived as a "rut", that's the first step of selling someone something: convince them they have a problem.

It's easy to get a non-QWERTY keyboard. I'm typing on a split orthlinear one now. I'm sure we agree it would not be productive for society if 99% of regular QWERTY keyboards deviated a little in search of that new innovation that will turn their company into the next Xerox or Hoover or Google. People need some stability to learn how to make the most of new features.

Technology evolves in cycles, there's a boom of innovation and mass adoption which inevitably levels out with stabilisation and maturity. It's probably time for browser vendors to accept it's time to transition into stability and maturity. The cost of not doing that is things like adblockers, noscript, justthebrowser etc will gain popularity and remove any anti-consumer innovations they try. Maybe they'll get to a position where they realise their "innovative" features are being disable by so many users that it makes sense to shift dev spending to maintenance and improvement of existing features, instead of "innovation".
