I have no idea. Very interesting question, i would say it was around glory era, that i started realizing some wrong things about this and getting into the whole conservatorship stuff. Maybe when the whole "Britney on rehab against her will" situation happened.
But it is still intresting to me how i never noticed something wrong AT ALL before, besides her not having the custody of her kids.
I just remember how i wanted Britney to comeback FIERCE like she used to and judging her FF performances, how selfish i was
