I might as well state my position.
I won't be watching the film (I have no interest in losing my lunch thanks) and have other objections to Netflix as is.
I think there's a case for it having a worthwhile message but being executed badly.
Youtube had a pedophile problem and a number of outlets went after it demanding action be taken etc because such "people" were going on mostly innocent videos and time code tagging certain stuff. So it's literally been shown that Pedophiles will be attracted to said material.
Other films faced backlash E.G. It Chapter 1 got a fair bit of backlash over having a child actress act out some scene meant to be about her being abused and there was a lot of concerns raised over that when from what I've heard it was handled far better.
Twerking by it's very definition is meant to be a sexual form of dance and those familiar with internet stuff will probably have heard about Onison getting underage girls to send him Twerking videos.
It seems kind of hypocritical for this film to be getting this level of defence when youtube was condemned for innocent videos being taken advantage of by said people and other films have had backlash for portraying negative things and handling it better but the potential for said things to have been exploited etc.
I think it was a pretty irresponsible move by netflix given the current state of the internet at present with for example the "MAPs" on twitter openly talking about lets say stuff that would make people stomachs churn.
They do this with a lot of movies/ shows, this isn't abnormal. Also, there isn't any blockage of free speech/ expression people can freely say what they want, they just cannot use footage that doesn't belong to them. Also, free speech only applies to governments, not private entities or platforms. Also freedom of speech =\= freedom from consequences. People can still sue if you make up shit about them and spread it online.
Technically if you're criticising the show or film itself you're allowed to use (under fair use) the amount of footage required to make your point. It's why Ethan Klein (H3H3) won the lawsuit against him by that weird freerunning pick up artist guy because Ethan's video was clear fair use and use only section of the original.
Oh also Content ID was created by Youtube to allow it to maintain safe harbour and be legally protected by the US government from being sued for people uploading copyrighted works. It's also why they respect most DMCA claims which also is part of the the US government legislation. So yes this would be government level as it would count as an attack on something the government has deemed free expression in the form of criticism. This is an area the government themselves have stepped into basically to make it so yeh you can't face a private company like Netflix being allowed to wipe criticism from the internet or bock it out. They could make deals to have it suppressed in the background, not recommended or promoted, ranked down in searches or youtube just demonitise it. However outright blocking the video is something they can't do for legally protected speech.
