Yes, the title is right: Britney supports the #FreeBritney movement and basically called us an “informed fan base”.

In another part of the filing, they also call Andrew Wallett a “semi-retired attorney who resigned suddenly after serving as her conservator for many years”.

Far from being a conspiracy theory or a “joke” as JAMES reportedly told the media, in large part this scrutiny is a reasonable and even predictable result of JAMES’ aggressive use oft he sealing procedure over the years to minimize the amount of meaningful information made available to the public. Whatever merits his strategy might have had years ago when BRITNEY was trying to restart her career, at this point in her life when she is trying to regain some measure of personal autonomy, BRITNEY welcomes and appreciates the informed support of her many fans. Although the sealing motion is supposedly for her “protection”, BRITNEY herself is vehemently opposed to this effort by her father to keep her legal struggle hidden away in the closet as a family secret.
The moment that JAMES obtained from this Court the power to handle BRITNEY’s affairs on her behalf, he surrendered a large measure of privacy as to the manner in which he exercises that power. Transparency is an essential component in order for this Court to earn and retain the public’s confidence with respect to protective proceedings like this one. In this case, it is not an exaggeration to say that the whole world is watching.
