Re: I think some people might have missed something...
I definitely see the tricky bit since in the same token I can see how targeting ads would equally qualify. It's entirely possible that I see more ads for a pickup truck and my wife sees more ads for an SUV but does it fall under equal opportunity?
It may be the same, but in that case if it was the same it doesn't mean what they are doing with the job ads is OK (because everyone else does it with other types of ads), it means that those other types of ads may also be in breach of the law.
However, I will note that I know that there are many laws explicitly around the labour market - hiring, discrimination, and so on - which may not exist around, say, retail product (or vehicle retail) sales.
Just because one could be legal doesn't mean the other is. it could also be perfectly plausible that one type of targeted advertising - for cars - could be perfectly legal while the same type of targeting advertising around specific categories, such as employment or housing, could be illegal.
