Sadly, too many people haven't been around for long enough to have seen it all before, and they fall for the new shiny every time. Then we get a few years of bad results where one product dominates and that part of the industry only evolves in the directions that suit the business controlling that one product, until eventually sufficient opposition has built up that a viable competitor is produced and we start to move forward again.
The Chrome teams (the ones that deal with standards, improving chrome, etc) are certainly filled with good people trying to improve the web, but there is such a conflict of interest there with a more open web or a web with certain features. Those employees are obligated to be on the wrong side of those discussions in really insidious/subtle ways sometimes, and those at the level at which strategy is conducted have a clearer view but have an even stronger incentive.
