The traditional publishers no doubt see open access as a threat to their dominance and economic survival. However in the era of increasing public and government demands it seems inevitable that open access is going to continue to grow.
It's important to understand the implications of open access re: nature of funding. The model is inverted, with costs of publishing falling on the author (or institutional backer) rather than the reader. Traditionally, the cost burden was on the subscriber, with open access it falls on the creator of the content.
Perhaps that's not more "fair" a distribution of burden, but there's value in ability to share research widely. Scientific knowledge is only as meaningful as the degree to which it is available to anyone who wants to learn about it.
