The price change itself isn't enough reason to leave them, but the way that they've handled the price change and their responses to customers is definitely pushing me that way.

It feels like a very tone-deaf response from Betterment that, while people are disappointed in the price hike, the loss of trust is coming entirely from the way Betterment is handling it and responding. It's hard to trust a company with your retirement when they literally seem like they don't care at all about the loss of trust.
