The Strokes are still relevant (at least their early work is). I still hear Last Night, Someday etc. in public and out at bars, one of their songs was used in an ad recently, you see repressings of the first album at record stores and their sound is still influential to a degree. Those might sound like weak justifications, but again I think that's just the reality of how music is consumed and conceived of by the populace.
To just say that everyone has a different opinion negates the entire existence of a cultural/artistic canon and ends all points of discussion. Is it true? To a degree, but we all accept that some output rises above the rest and makes more of a mark or has more of a lasting appeal. The Strokes and The White Stripes were the two best bands of that era/loose consortium of bands and I think that they deserve to be recognized for that.
Interesting side note, I noticed that there's already a small revival of the "The" bands which I specifically see embodied in a group like The Struts. They don't sound very fresh or interesting to me, but it's clear they're inspired by the same kind of vague nostalgia that drove the lesser bands of the 00s.
