It's not support if you have to complain on a public forum though.
I think that parent post was just implying that AWS cares about it's image and will provide support even if you don't go down the correct channels.
Google doesn't give a shit regardless of the method of request.
They even go into your cloud architecture and tell you where you fucked up.
I will say though that companies which take support seriously do monitor all sorts of channels as well.
Very much this. At my company we have many other means of support readily available, but some people instinctively reach for Twitter for peer support. Being active on Twitter means our support team can help even those people who don't think to use our official channels, which is good for the customer and good for our image.
