As a conspriacy theorist myself, heres my views:

If its true that Typhoon failed to qualify and were let in anyway, then it probably is because they were RAF/cadets, but that wouldve been done purely to have them representing in the arena, rather than to have them win it. (so 1 could be partially true, but not fully)

I cant see 2 working because the government made defence cutbacks recently. But of course it would be promoting big business if they were true (a goverment policy). However they couldnt rig all 7 fights as the other teams would refuse to play ball (and the house robots never tried to throw the fights either like theyve done in the past), but the closeness of the final provided an opportunity if they wanted it. But still an unlikely scenario though, as I bet hardly anyone knew about the BAE connection.

3 suggests a clever and tactical usage of the rules - not the first time its been used to win a final of course.

4 - I thought that the reason for the active weapon rule was because Mentorn didnt like Tornado for beating their beloved Razer (first reaching the final by using no active weapons on Hypnodisc/Dominator/Firestorm then adding defensive weaponry to win the war), hence trying to get them banned (but of course the Tornado guys are far too inventive for that to happen). And as Storm is a Tornado clone, it comes under the umbrella too (even though they fitted an effective weapon that didnt actually compromise the armour - maybe that pissed Mentorn off).

But if Mentorn did influence the judges it wouldve been more likely that they just wanted a spinner to win (which was also thought of as a reason for the active weapon rule).

5 - heh.
