More of a meta comment, but are all organisations stuck with their slogans forever?

NFL rotates these messages and this game it moves from “End racism” to “Choose love”. Next it will rotate again and people will be upset they removed the “Choose love” slogan because they are anti-LGBT?

Google changes their motto from “Don’t be evil” to “Do the right thing” and everyone is upset. One day they will change it again and everyone will be upset because of course they are not doing the right thing anymore?

Both NFL and Google are evil and deserve no sympathy, but I wonder what’s the expectation here? Never change any slogan?
