I don't mind it in sports like baseball or football where offense and defense are so separated. You can't expect a team to keep kneeling on the ball or strike out three times on purpose. Even pulling all of your starters isn't common since there are much fewer bench players.
In basketball it can get a little annoying when a team like GSW is still running out Curry, Klay, Green, etc well into the 4th even when they're up by 40. It more seems like stat chasing than anything else at that point. When the end of the bench players are in, though, then I consider it totally okay for those guys to play hard. Many of them barely get an opportunity to play.
