I think this is mentioned upthread, but it bears repeating, the financial reasons for running a long EA are totally valid. These things are not cheap efforts, and running an EA like a kickstarter is great way to augment other funding sources. (Provided you'll be able to deliver)
I think it's unfortunate that Larian weren't more clear about their intentions for EA, and as a result, a lot of us had unrealistic expectations.
But I would absolutely do it again. Playing EA has been a blast, and I don't regret participating even a little. I just had to recalibrate my expectations
