> The fact that you give something away at no charge (but actually make money or even if you don't make money) is not a reason you can then walk away and not have any responsibility at all for anything and everything. (Or shouldn't be).

I'm very sympathetic to OP's situation, I have also lost an account with years of irreplaceable emails to Google's finicky algorithms. But this right here is a slippery slope I would never wish for. Offering a free product should absolutely not entitle any random user to any kind of support. I should be able to release a product (whether open-source, free, or paid) and decide for myself and my business the level of support I want to provide, without an obligation to respond to everyone, or maintain it forever.

It really sucks that Google's business plan is totally cool with leaving some of us behind, but I'd rather take the risk that comes with the territory rather than not see these products get created in the first place due to onerous obligations.
