Shirt sponsors aren't not a particularly new thing, though. But I guess in the past Arsenal in particular had sponsors with slightly less controversial owners - iirc JVC and SEGA/Dreamcast weren't directly involved in any slave labour controversies or human rights abuses like the UAE is :)
And gay rights, which both the UAE and Rwanda (where gay sex is legal now, but just another case where the gov has changed the law to appeal to Western sensibilities but sentiments of the public have no changed) are terrible at.
