What’s the being deal about microwaving water for tea?

I’m not a big tea drinker myself. My parents have always used a kettle to make chai. Though they use microwaved water to make green tea. I don’t really care either way imo.

I see people acting like using a microwave to heat water in a cup instead of using a kettle is some sort of grave sin that’ll guarantee your spot in the deepest, hottest part of hell.

Why? Isn’t it a microwave’s entire purpose to heat up water molecules? A kettle does this with a different method. Both end in the same result, one is just less work than the other. Does it taste different? Or do people just not like what is different from what they are used to? I don’t get it
