So far I understand this:
1. RB is clearly over the budget cap, either by a few 100000s or 1.8 mil
2. Their excuses are lame to say the least
3. They designed this, if we believe Zak Brown that they were on the limit.
4. There is an active campaign from RB fanboys, media etc to direct the discussion to "that was not for development".
5. This campaign is successful so far
6. RB will accept the ABA, as long as it doesn't heart them a lot.
The "changed the rules" mantra is completely B.S.. Because they would have mentioned that from day 1. They didn't. Even RB officials said completely different things just a few days ago!
To me it looks like they had a list of predetermined excuses. Since most of them didn't get them to were they wanted, started playing the rule thingy to make FIA look as the bad actor.
In any case, unless FIA get' s pissed off, I don't see any harsh punishment...
