I also hear people make the same claims against Alexa, but I usually start explaining what cookies are and how ad networks collects your data to more effectively target you. It doesn’t make fiscal sense to do mass audio surveillance when you already freely hand over your data.
I can also attest to hearing “eggs in a basket” and “toad in a hole” growing up. My son has just dubbed the dish “egg bread” and requested it almost daily. He also calls fried eggs “dip eggs” and boiled eggs “shape eggs.” He was probably 3 when he solidified these terms, but they have all stuck, 6 years later.
