I don't know. Honestly- I've said this quite a lot- I don't know why they have done some of the things they have.
Tucker might have the right of it- more a PR exercise as they were getting roundly berated at the time.
Maybe they felt responsible to explain to fans why they were changing it BECAUSE they were looking to change something largely driven by fan requests?
What I will say is, despite taking O'Farrell back, at no point have HBG changed that statement/given a new one. So, on face value of it, they felt, as a group, that they were left out of significant financial decisions at a board level.
How that came about is open to speculation.
What I believe/suspect is- with the way HBG shifted gears on the board members post the Richardson resignation- having Richardson out of the club eased the situation.
Read into that what you like, but the two things together, combined with O'Farrell & Richardson signing off on the ground allocations.. I imagine this is the focal point.
If I was a betting man, my guess would be that HBG felt Richardson (and to a lesser degree O'Farrell/independent board members) was making decisions that HBG felt should have been run past them as the main financial partner of the Wests Tigers (not including grants etc).
