If the Cathy Cluck and Jade video are truly unrelated incidents, then that's quite a coincidence. It's like if someone is robbing your house, and at the same time someone else is breaking into your car. Plus fucking Jade AND sharing the video are not canon events, so another party being behind the leak/Stephen having access to the DIKs' files would still need to be explained on other paths. If it's all connected, it's easier to explain.
yes and no
if you suffer two thefts to say that the thief is the same seems to me quite a gamble...
those are 2 actions that have very little in common apart from Rusty's laptop (and for Jade it's not 100% certain) as a method and intentions. so instead of explaining who else did it you should explain why
I see it as equally complicated to explain why Cathy's photo is published without a second thought, while Jade's much more striking video is instead kept hidden or even ‘donated’ to Burke
is Burke the culprit? then you have to explain to me why he wanted to ruin Cathy too
was it Nick/Vinnie? then you need to explain to me their connection to Burke.
the only profile that fits both of them is the Nerds, but there you have to invent a whole new story, putting a whole new pawn on the chessboard.
I'm not saying it's not possible that there's only one culprit, just that it's not such an obvious deduction, even taking into account DPC's habit of deliberately inserting false clues
