If you run your own design agency, you've got your own company's reputation and yours on the line, so be as opinionated as you find necessary, but otherwise if you're just an employee without an inordinate amount of clear authority within the scope of your discipline at the large company (you know if you do or don't) then don't try and create a mutiny, it will more than likely be a childish assumption of personal risk on your part, much more so than it costs the company, much more so than anyone else needs to care, because someone on a forum told you to be passionate about round rects or small icons or whatever. If you need to tell your boss "google NN group", you probably don't have the trust or experience to be successful with such a play.
It's okay to have a personal hatred of it and do what you can to steer the work appropriately, but when you're tasked with a dumbass plan, let it be the decision-makers' dumbass plan, unless it's your decision to make. Let it be the project we tried and it didn't and couldn't have worked out, which sometimes happens, but you learn and then leave if it's pervasive and you have other options.
It would be remarkably stupid to single yourself out as the person who thinks of themselves as the reincarnation of Steve Jobs and risk your livelihood to save Apple's reputation. The unlikely upside is that you get your way and that can boost your confidence, but the downside is that you fumble your best shot at financial security for the rest of your life because you thought you'd be received well.
That's not to say you shouldn't say no to nothing, or have love for your craft, just don't pretend it's your job to, unless it is, which it's probably not. Disagree and let it be a failure if it's going to be, feel vindicated if it is, but the money is there for you if not. The people who worked on the Vision Pro aren't responsible for it being a dud product, and they can be proud of what they did design-wise and technologically despite that.
