GMO have a bad reputation because the most popular strains, Monsanto's glyphosate resistant strains are indeed concerning from a toxicity, ecologic and economic standpoint.

GM is a wonderful technology, with applications not only in agriculture, but also health. Insulin is produced by genetically modified bacterias, and modified white blood cells are now experimentally used to treat cancer.

There are probably other uses, but I'm not aware of them.
