To me, it just smacks of arrogance
"Yeah, I bought the shirt with Luis on the back, but they'll refund me if he leaves. They'll have to. I don't have to make an informed choice. I'll just do what I want and then I'll cry foul when it turns out I've made a bad decision, rather than holding myself accountable"
I should point out that I wasn't having a specific go at Liverpool fans there but more the consumer culture we live in these days.
When someone makes a bad purchase these days they seemingly never hold themselves accountable and think that Heaven and Earth should be moved by the seller to dig them out of their own hole.
If you purchase anything without thinking about the purchase then it's you and you alone who should be held repsonsible. It's not the fault of Liverpool FC if you choose to get a player's name on your shirt when they are publically negociating with another club to sell him
