Don't stop swearing. Say "fuck it" loudly and proudly. If you cannot swear, argues TAL18 (Nassim TALEB, Skin in the game, London: Penguin, 2018), you're probably not in a position of independence.
That's why there's the old joke. That candor is for the wealthy.
Maybe it really is that.
Prohibitions on speech arise, as Normal MAILER said (according to Ted MORGAN, Literary outlaw, New York: Norton, 2012), to repress the individual. To make them feel weak, and force them to use force in a permitted outlet, like politically contrived conflict. Whereas a swearing society is probably a more peaceful society. Paradoxically.
Youtube clearly demonetized swearing to weaken noninstitutional posters. They did not fear, if they wanted income, and were popular, saying whatever they wanted to say. Now they are afraid.
In contrast, institutional channels are empowered. This was to switch youtube to attract higher paying institutional channels, who being on television, cannot be as free to say whatever is desired when desired. To voice complaints in powerful language. They cannot compete with the internet, so Youtube leveled that field.
But the field is not level, because most content creators do not have equivalent marketing, nor market position. Not swearing when the situation calls for it is to fall for a scam.
I think the problem is - if you are a really good marketer - you know that using profanity excessively will turn off most of your base. I wouldn't say my reasons are economically motivated - it's a habit that got out of control - a habit that I developed under very different circumstances!
