I had a coworker who watched some idiotic video where someone showed "proof" that microwaved water kills plants. I never saw that video so I imagined they poured the boiling water onto the plants. He was adamant that it was true. "I know what I saw", blabla.
Well, microwaves can affect your food. Though only a handful (of hundreds) of antioxidans in berries, same as if you leave them a few days in the fridge. But no issues with water.
