I can see why the team got overwhelmed. I wouldn't want to have to deal with that.
Next time try doing it in a way that you control it.
My main point wasn't that, though. It's simply a bad and low-effort way to handle the situation, and like one of the other replies points out, there are better options. They could have just as well disabled posting and maybe even viewing of submissions and communities for the time being. Just shutting it all down immediately without notice leaves a bad taste in my mouth, and I will not be among the people returning for their next relaunch. I am sure others feel the same way, and I don't think it is a wise decision to needlessly put off your early adopters if you're hoping for them to come back "next time".
Now it's gone, again. Without a head's up or a way to get a backup out of it, it seems like. Can't say I am a fan of that.

If the authors wanted money for their software, they would have sold it instead of giving it away for free as a gift.
By releasing software under free software licenses you are explicitly stating that you do not expect or anticipate payment for it. The licenses (that they freely chose) are clear. Free software, in addition to being free as in speech, is also always free as in beer.
My friend bought me lunch. I used that energy at my job. Do I owe them part of my paycheck?
Someone built this and is letting you have it. For free. There is no legal obligation or law of the universe here, sure, but if you're in the top 1% of benefactors of this pro bono work, you have the opportunity to do some good and make sure that others, like you, get the chance to benefit from this free work in the future.
There is a pretty straightforward argument to be made that this falls under the "with great power comes great opportunity" umbrella of moral reasoning, since this work empowered CA to create the game that earned him a lot of money.
I have used their products and have more favor toward them than I do for the corporations you're referring to, but ultimately my question is the same.
