Yep. VERY weird and that's why I like it. I don't want to spoil anything but later you see who's really behind it (not the hackers, they are just little helpers). This scenario is quite realistic (even though it's - of course - childish that a small group of hackers bring down such a big company).
I watched the first series a while ago, loved it, not watched the second series yet. I did find ti a bit strange, especially when it came to the drug taking parts, but the hacking parts were really good.
