Agreed. But cancel culture isn't about discussion, its about shutting down the opposing argument. If some activists decide that they don't like GB news because the GB news agenda is contrary to theirs, they don't get into discussion about it, they take aggressive action in an attempt to shut down GB news and that is what advertisers are scared of.It's the free market. If someone doesnt like your product or where its being advertised and you want those people to buy it - you are not forced into anything.
They're scared that activists will take to social media and other forms of modern coms in an attempt to damage their business or reputation with the direct aim of forcing them to disassociate themselves from GB news. In these cases, the advertisers have removed their advertising revenue quickly to avoid any potential cancel culture damage.
