Some politicians have learned that when it comes to free promotion, giving fake news or misleading statements can be just as effective for campaign purposes even though people can easily disprove the lies.
WT is a business corporation. They have found that spinning any exJW channels as "persecution" helps promote the business model. Leaking the annual meeting is one way to increase the amount of exJW videos in a way that isn't typically too "detrimental" to the WT image as long as they are controlling most of the exJW youtubers who have the most followed content.
WT has been known to use its illicit contacts to depress certain media stories while promoting its own desired agenda.
The government benefited from WT in the past, but at a certain point their relationship becomes a liability rather than a mutual thing.
The government would rather cut Watchtower off completely than have the masonic connection revealed.
