The comparison is apt, just not entirely. It isn't a comparison of IE6 vs Webkit, it's of developer reactions to them.

For a long time, IE6 ruled the roost, so developers used IE6 as their development target. Browsers that moved beyond it, or implemented things differently (often correctly) were ignored.

On mobile, webkit rules the roost. Developers use it as their development target. Browsers that move beyond it or implement things differently (by using non-webkit prefixed CSS) are ignored.

I mentioned in another comment that when I think of IE6, I think of the hours spent fiddling with the HTML/CSS that works in FF/Chrome but not in IE6 because of browser bugs that were never fixed and standards not followed. It's why I think it's a bad comparison.
