Edit - Much better summary of the whole thing here.

Here's the statement:

I am writing this statement as unfortunately Novara Media have left me little choice. In light of the organization’s refusal to address the actions of one of its senior employees that led to the persecution of three young women of color and their ultimate conviction under the UK’s racist and Islamophobic counterterrorism laws, I have asked that my interviews be removed from their platforms.

Amidst an ongoing genocide, and at a time in which Palestinian political expression is under attack, this staff member chose to collaborate with the British police and the right wing media in their campaign of persecution, incitement, and hate-mongering. This has caused serious legal and social repercussions and psychological harm to the individuals involved.

I have been the target of countless smear campaigns which I have usually disregarded as background noise. However, I chose to speak out in this instance, even though it did not directly affect me, because the silence of Novara, an organization self-described as “always politically committed,” represents a complete failure in upholding the principles of accountability, solidarity, and anti-racism, and should concern us all.

One might argue that Aaron Bastani’s actions fall within the realm of free speech, however, exploiting an atmosphere that is already hostile to Palestinians and collaborating with the British establishment to smear, police, and punish us and our allies sounds less like free speech and more like harassment and incitement. Where does Novara, an institution that purports itself to be a voice on the side of justice, stand when one of its staff members causes such harm? Bastani’s actions—and his colleagues’ silence—must not be separated from this context. Demanding accountability is not “sowing division,” what is divisive is putting a target on the most vulnerable among us, the most susceptible to state violence.

Novara’s above-average reporting on Palestine is not a gift they are bestowing upon us, it is as simple as journalists doing their job. It does not give them a special license to police our movement. (There is a joke to be made here about British institutions and colonial legacies.) If Novara wants to contribute to the larger anti-capitalist, anti-racist movement, it has a responsibility to hold itself accountable for violence that is produced within its own institution.

TLDR - There was a pro-Palestinian rally in London back in October. Photos of some protesters (the women in color mentioned above) went viral among right-wing circles because they had images of the Hamas paragliders on their jackets. Aaron Bastani joined in the denouncements. Apparently, the UK Police has since prosecuted these women and Novara Media, the organization Bastani co-founded has remained silent till now.
