Actually, I will criticise players because they can make choices, informed choices, moral or ethical choices, - they do not have to decide to play in such societies and countries, irrespective of the vast sums of money on offer - for they are neither robots nor puppets.
Needless to say, I will also criticise owners, and agents, - some have played egregious roles in this charade - and yes, will also criticise the lamentable failure of regulatory authorities to address the issue of sportswashing (and the earlier issue of sales to some owners, as questions clearly needed to be asked, and weren't).
And I will also point the finger of blame at fans; yes, there is not an awful lot that they can do, but the deafening and morally myopic silence of Newcastle fans re their current owners (they were a lot more vocal when Mike Ashley owned the club), and the troubling silence of some from Manchester United about overtures from other sportswashing sources does leave a sour taste.
