In the "Catabolite repressor operon" section it says "inducer is bound to repressor so DNA transcription cannot continue." In the environment of high glucose described, the inducer bound to the repressor would not be bound to DNA and that would ALLOW transcription to occur, but the high glucose decreases cAMP which decreases the amount of transcription occurring.
