That's back when she was still in a conservatorship that she said gave her zero control of her life, her career, and her day-to-day activities."
And there have since been several stories which her team corroborated saying that this was one of the first contracts she signed post-conservatorship. She posted about it postively (and we know if she felt otherwise, she would certainly say so). If you want to approach this conspiratorially, by all means go ahead, but it's divorced from reality.
That said, I am sure the producers would have LOVED if she had attended or done more. But as with everything else, she's living her life on her own terms which is what everyone said they wanted from Free Britney. It wasn't until she was actually free that people started realizing they'd only be satisfied if she was free and working.
