Okay, that offers a bit more insight into what happened. The original message sounded a touch vindictive, but this gives a bit more background into the reasoning.
While I would still echo the caution that others posted about above, this really sounds like a good time for the players to recognize their runners may want to seek retirement. The good and bad thing about Shadowrun is that it is a quasi-realistic system, where if you screw something up(especially intentionally, as in this case), then the world in general is going to be looking for someone to blame.
I'm hesitant to say the players deserved what they got, because this is still a messy situation. But it is an example of when a team gets a God complex. And SK, being the world's most powerful megacorp, would likely have every right to go after them, considering this event caused a very-profitable new product to have to be cancelled.
I still say it's good to try and remain impartial as a player or GM, and conduct things in-game, but with that said, if it were me I would have had SK issue orders to go after their relatives, their contacts, basically anyone associated with them. One of the best ways to screw with runners who think they're untouchable is to cut them off from EVERYONE and EVERYTHING. Then, when they're strung out and feeling powerless, hit them with that response team. Note that this isn't a punishment as a GM, this is something I fully see Lofwyr or his underlings doing. Because dragons tend to not be very forgiving.
Anyway, that's my perspective again. All in all, the other way is to speak to the players and try to establish to them that this ISN'T Dungeons and Dragons, and all actions have consequences.
