I'd say it depends - evaluate the vibes. I spent 8y and recently 7y at a company where I genuinely responded with what I thought. But I'd say it's a matter of the audience - some people want to hear certain things and deciding if you can share these thoughts is up to you. It also allowed me to make decisions - if people don't care what I think and want sycophancy is this the company I want to be working at? I understand though it depends on one circumstances = you have to grin and bear it
