I think one of the main factors pushing the trend in the direction of more founders retaining control is the increased availability of angel money. If it came down to my cofounders and I having to give up control to raise a Series A (or any series for that matter) I'm sure we'd turn to Angel List to raise a similar amount from well connected and useful investors, without having to give up control - if that were a viable option. Increasingly it seems like raising a large angel round is an option, which is great for entrepreneurs.
