As has been said, we should give one of these media groups such a kicking that the others fall into line. One of the major issues is continually describing us as 'state owned' when all the documentation shows that ADUG is owned by an individual and CFG, which does actually 'own' City, has three major shareholders.
There's also the accompanying narrative that we couldn't operate at the level we do without continual owner investment. That's also demonstrably false. It'd be nice if the club made it clear once and for all what the situation is.
They could then emphasise that there is no further excuse for misinformation and that any further repetition of these falsehoods would be treated as deliberate disinformation or even what's known as malinformation (which is disinformation that is deliberately designed to cause harm).
