Let's make a list of everything we know about the hijackers

NOTE: For the sake of convenience, let's refer to the guy in the Max Headroom mask as "Max", the girl in the maid costume with the fly swatter as "Maid", and the cameraman as "Cameraman".

1. "Max" was a fan of Clutch Cargo, given that he could both hum the theme song and name the title of the final episode I Still See the X. This suggests he was probably born in the mid to late 50s since "Clutch Cargo" was a popular kids show in the early to mid 60s. This would put his approximate age in 1987, at the time of the hacking, at around 30 to 35. Of course, it's also possible that he was born later and only became familiar with Clutch Cargo via reruns.

2. The video was pre recorded, not performed live, given the jump cut towards the end which would be impossible otherwise.

3. Although "Max" was willing to show us his bare ass, a dildo, and some spanking, he was oddly reticent to swear. He uses the word "freakin" twice instead of "fucking" and never even comes close to cursing in any other capacity at all. This seems odd. He's willing to commit a federal crime, show his ass, show a sex toy, and get spanked on tv, but he won't swear? Very curious.

4. They had to have equipment that was both powerful enough and close enough to the broadcast towers of the stations they hacked in order to be able to hack them. Their tech had to be just strong enough to bump WGN's signal for a short period without being able to break in with audio, and then strong enough to fully break into the WTTW broadcast for however long they wanted with full audio. This has always implied to me that it almost certainly had to be an inside job, so the hackers had to be employees (current in 1987 or former by 1987) of a tv station in Chicago. I think it's quite likely they were employees of WTTW but disgruntled former employees of WGN. Either that or, if it wasn't an inside job, they had to be hackers with extensive knowledge and almost unattainable equipment capabilities for private individuals at the time, as we found out during the K and J era of this investigation.

5. It's possible that "Max" himself was neither a tech expert nor an employee/former employee with WGN, WTTW, or any other station. He could have just been a friend of the real mastermind who might have been "Cameraman" or even someone else entirely. It's quite possible that the people who made the video took no part in the actual hacking itself at all. Maybe they knew someone who worked at WTTW or WGN and they gave the tape to them to broadcast. Maybe the person they knew on the inside was the mastermind and got them to make the video, or maybe the video makers were the masterminds but didn't know how to actually hack in themselves but talked their friend who worked at WTTW or WGN into doing it for them.

6. "Max" seems to be a fiscal conservative. He insults Chuck Swirsky by calling him a liberal, implying that he thinks being a liberal is a bad thing. However, given his willingness to possess and show a sex toy and his ass on tv, I couldn't really say he's a social conservative. My guess is he's a libertarian Republican type of guy.

7. "Max" seems to personally harbour a grudge/contempt for Chuck Swirsky and WGN, since he explicitly insults both of them during the video. My guess is, he is a disgruntled former employee of WGN. I think his insult against Chuck was actually more of a throwaway comment, insofar as Chuck was probably just the first famous reporter that came to his mind when he wanted to make the point that, as a presenter on tv, he's better than most reporters already working. It'd be like if I did something similar today and to talk myself up I said something like "I think I'm better at this gig than Don Lemon, freakin liberal!" It's not that I have a personal beef with Don Lemon, he's just a tv personality I'm sure most people will know, so he's kind of a surrogate for the whole industry in that context. That's how "Max's" reference to Chuck comes across to me. However, him actually knowing to call WGN "the world's greatest newspaper" shows a bit more intimacy in his relationship with that brand. I don't know, but I'm not sure most people would just casually think to call WGN by it's full name like that. Seems like his beef with them is a bit more explicit and personal.

What else do we know?

Is there anything I've got wrong or missed here?

I'm very keen to hear more thoughts on this.
