What does Ezekiel 20:28 mean?

When I brought them into the land I’d promised, they saw every high hill and leafy tree and made offerings there. They brought sacrifices and poured out drink offerings, making those places into shrines that still disgust Me. Ezekiel 20:28 - Modern Text Bible

(Even after entering the promised land, the people kept turning to idol worship, copying the practices of the nations around them.)
