Fine. That’s not what’s going on here.
4chan isn’t in the UK. 4chan doesn’t have UK employees or offices. 4chan doesn’t book income on the UK. 4chan didn’t have any thing to do with the UK at all.
If this isn’t convincing, consider this: legally what is the difference from Afghanistan requesting anything not legally in compliance with Taliban’s laws be restricted? Would you support that? Legally that is what is going on here.
Afghanistan can block anything they want within their borders and hold anyone in contempt if they refuse to comply. Whether I support that or not is immaterial - I would have to comply in order to continue making other content or services available to Afghanistan residents. Being entirely blocked would be worse.
