Opera is already a pretty small actor so stuff like this probably hurts them more than the bigger guys. This incident will probably show in the bottom-line later on.
Hope they get their things sorted out, and I really hope they learn enough to avoid having anything like this happening in the future. Things like this are never OK if there is a second time around.

I'm not much of a Opera fan, but we need to give credit where credit is due.
Of course, with the web moving towards HTTPS, technologies like SPDY are forward thinking and proxies get shelved.
As the other commenter outlined, for these kind of devices Opera is a keyhole to the internet.
And you will notice that even on modern hardware with good access to the internet, Opera works smoother/faster than other browsers (it's at least the case on my android tablet).
I would imagine that keeping this a secret would be worth a lot more to the right people.
