I am not too worried about words and language. Sure it is possibility it could have a some affect but personally I think we have mostly already solved this issue buy using different words for things. You already linked an example. Instead of saying suicide you say unaliving oneself. It is a bit more of a mouth full but it signifies the same thing. As far as the younger generation is concerned “Old” people will use suicide and young people will using “unaliving” or whatever else they come up with.
Now topics themselves I do think we have an issues because some topics are basically off limits if you want to actually make money off advertisers. I don’t really have a good solution besides funding the creators directly like Patron for example.
