Apple Thoughts: Natural Progression or Dirty Trick? You Be The Judge

"Google Jan. 29 said it would cease fully supporting Microsoft Internet Explorer 6.0 for its Google Docs and Google Sites applications March 1. This pledge extends to other older Web browser versions, including Mozilla Firefox 2.0, Apple Safari 2.0, as well as Google's own Chrome 3.0. The move is Google's push to rid the messaging and collaboration world of the dated, insecure IE6 and put Google Chrome in its place. Chrome has 4.63 percent of the browser market and would love to chomp away at IE's 63 percent share."

Doesn't seem on the surface to be anything as sinister as forcing their way into marketshare, appears to me like its natural progression of things as software advances. But I suppose since IE 6 has over 60% of the market for browsers that it would be natural to assume Google was up to some skullduggery wouldn't it? What are your thoughts?
