Yes bitterpill... It has to be actual magic in order to be lawbreaking... Basically, any ability under the Spellcraft section, in the Supernatural Powers chapter, has to abide by the 7 laws... One could technically argue about sponsored magic... Hell, one could even argue that if its true sponsored magic, IE you have evocation, channeling, thaum, or ritual, that the magic that killed someone is yours, just with someone else's juice power it up, while full blown Unseelie, or Seelie Magic might not break the laws... Honestly, I don't know what to think of it... I could fall either way, mostly falling towards it still being lawbreaking...
But we do have precedent that Sponsored Magic, like full blown Unseelie or Seelie Magic, can interact perfectly fine with technology without harming it... IE one of the knights of the courts may not have any issue with technology... The precedent was set in Last Call, the last short story taking place between Small Favor and Turn Coat... ((book 10.4, Last Call))
The baddie in the story had placed a very potent, and complex spell on Mac's beer. But later in the story, it was found she left a paper trail with a credit card at some bull Black Magic store. Harry said that since she was obviously very good with magic, and could still manage to maintain the magnetic strip on the card, that she wasn't using normal mortal magic. That she had to be some sort of supernatural creature, with access to a different kind of magic.
Now that COULD be a big leap in logic, but I think that its followable... Anyway, the whole reason for that, is that potentially, sponsored magic that comes fully from the sponsor, and isn't just a plug in battery, may be following a different set of rules...
