Not really, it shows either that she is a doting Grandmother or has learned from her past experience what happens when you interfere. Once the transfer was allowed, what could she possibly do without making herself, William and Charles look complete idiots.
But that is exactly my point. Being a doting grandmother is fine, but HM is also the reigning monarch and it is not okay to endulge her grandson, a future monarch, at the expense of her subjects, especially the ones in the military, nor turn a blind eye if he proceeds against her advice. The transfer should not have happened in the first place, if it is really such a brouhaha, if she is doing her job as monarch, head of the military and yes, grandmother.
Or, as she did with Diana, she hopes it will all just blow over. The rules were manipulated to accommodate Williams personal ambitions and that along with his other deceptions is shameful. (Which is why the base mods are at full tilt monitoring and removing)!
Monitoring and removing what, exactly?
Question is: when did she saw it and what could she actually do at this point in the story? I doubt she was informed before that her grandson would use a loophole which could be seen differently by the media than her advisors did - that this could lead to the next round of "abuse" stories etc. And afterwards: what do you think she could have done?
First, let's assume for the sake of argument that this is really as big a deal as some are making of it. Personally, I'm not convinced that it is.
If she wasn't informed about something like this before it happened, then someone should lose their job. If it is indeed an event that could precipate a crisis that endangers the monarchy, if her advisors did not see the possible ramifications then they are not very good at what they do and should, perhaps, be replaced. However, if her advisors are doing what they are supposed to do (advising her), she is still a very long reigning monarch who should know better than to blindly follow their advice 100% of the time.
Afterwards, there is nothing that can be done. Quite frankly, I think it was all done intentionally and there is no remorse about it, nor do they think there should be.
