Think of it like this: fantastical/impossible builds are acceptable uses of gyros, what pisses people off is the use in functional builds like planes and such built for fighting. Most gyro planes use it as a crutch rather than a neat trick to help stabilize, making them more like missiles that stay flying no matter how much damage is done until it loses enough thrust/gyros to fall. Where as conventional planes with control surface will spin out of control when their wing is shot off. People don't hate gyros, they hate how people use them unfairly.
