re: wiretap's role in the last line of defense against any takeovers of argent, which is sitting in the most cutthroat business flight at a very geographically and politically important location
it's pretty rare to see an all-out street fight, they're mostly figuring out who's here for nefarious purposes and getting them kicked out, one way or another
more like an information war
"kicked out" of course ranges all the way from 'government says youre Not Allowed Here Anymore' to 'outright assassinated if youre being stubborn enough'

a) well the sponsors try to get them to banter among each other about the product. this sometimes works and sometimes does Not.
(as for what, well, it's the lightning flight- there's probably somethin' new coming outta goldensparc's companies on the weekly. you usually can tell what's a decent product and what isn't by exactly how enthused they sound about it. well, how enthused the audio technician one sounds- the announcer is ppppppretty good at keeping a facade.)

b) technically they both talk. realistically, one of them does the majority and the second one chimes in between adjusting the audio and making sure they don't ramble off the schedule.
it's usually the news btw
lotta politics? wiretap radio covers much of the northern shifting expanse, they try to keep travellers up-to-date on what exactly's going on in the area and exactly how many companies are feuding with each other
...and a couple notes on what their fellow radio hosts are doing AKA the DJ is spamming techno music again probably

"this product is SO good i use it every day -"
"no you don't liar i'm stuck to you you absolutely do not"
"SHUT"

oh god actually listener calls...... the audio technician shuts up for 90% of it because they're having a TIME dealing with all these shoddy staticky phonecalls
Listener calls, but certain calls are known undercover announcements for trusted citizens.
Like "crazy old mary" but crazy old mary calling in actually means there's gonna be an invasion soon and everyone should keep an eye out.
So technician head's got a giant headache going on, but she can't do anything about it because lol that's actually important.
Windad call: a wild and crazy moment
spoofed Windad call: Signal to listeners that there's about to be a huge info leak, stay tuned.
