Indeed it does show loyalty and if it's just a bluff against an arbitrary FA decision then I guess it could pay off. But if they actually did go on strike, I would think most people would just be pissed at England's exclusion from the tournament.
Well it's pretty dumb for them to rebel cause of Rio's exclusion since it would mean the whole team is excluded from the competition. But if that's your priorities then by all means.. what's the interest of a nation compared to some delinquent's personal situation anyway..
