Uefa really are first rate idiots

Sorry of this has been covered elsewhere.
What the fuck is wrong with this? Moreover,, why has it taken till now to hand down the punishment?
Ajax have been ffined €10,000 (£8,300) by UEFA after their fans displayed a "provocative" banner that "created unrest" during their Champions League game against Manchester City. The display showed a sheikh holding a bag of money with a red line through it alongside a message reading "Against Modern Football!". However, in the same game the Ajax fans also showed a banner that read "€80 for the away section is ridiculous!", showing solidarity with the City fans who had paid that price to watch their team in Amsterdam.
