It's all about respect.
In my workplace, I'm asked not to post anything/give an opinion on social media about what is happening with competitors or else I'd get the boot/disciplined whilst under contract. It would be all over the newspapers and I would upset a lot of people/customers if I did. Football is no different.
It's quite unsavoury knowing that some players' are paying attention to other matches when their focus should be on ourselves keeping afloat, particularly when it's guys like Agnew/Carswell, who played next to no part in our match to proceed to post their support for others.
Again, there's no real problem with footballers using social media, they just need to be shown how to conduct themselves on it whilst attached to our club. The fact that they're being told how to behave publicly by the CEO epitomises that.
