Give it a few goes and eventually "advice" will become the bad word. People will realise that they're just getting the same response that dissuaded them originally from responding to requests for "feedback".
It's not the word you use, it's way you respond to what you receive.
My CEO currently asks for (and receives no) "questions".
"The principle of linguistic relativity holds that the structure of a language affects its speakers' world view or cognition." (emphasis mine)
It's not about words or diction. It's about language as a broad, thought-influencing and -limiting tool. It's about what is thinkable to someone who uses a particular language.
"Unlock attention from villagers by shouting 'Wolf!'"
Words only mean what the social structures surrounding them dictate that they mean. Attempting to change social structures by using different words ultimately results in nothing more than altering the meaning of those words to fit the social structures into whose service you're conscripting them. Cf. every generation of teenagers ever.
