1a. Web standards are good because they provide a baseline of combatibility for browsers. 1b. Webkit forks on all browsers could be good because it would provide a baseline of compatibility for all browsers.
2a. Web standards could be good because they prevent any one browser from setting defacto proprietary standards that lock other browsers out of the market. 2b. Webkit on all browsers could be good because it would prevent any browser from setting defacto proprietary standards that lock other browsers out of the market.
3a. Having webkit on all browsers would hurt standards by becoming a defacto standard providing a baseline of compatibility between browsers and still allowing competition. 3b. Having webkit on all browsers would provide a real baseline of compatibility between browsers while still allowing competition.
It's a little bit funny to watch actually.
