Journalists aren’t to blame… There’s plenty that have written about climate threats because there’s been a lot of Science saying it is for years. It’s the Editors and Media owner that censor those stories that are (partly) to blame.
Extrapolating from there, who influences the Media Owners/Editors? Whomever gives them money - Most likely it’s advertisers, but it’s also rich assholes who buy up Media outlets to control them.
Beyond that, we can also point the finger at Government - They permit these changes of ownership and often exert their own influence.
And, if you want to go full circle, we the population choose what the watch and read, and what we believe.
In short, it’s a societal problem because at the end of the day, we’ve chosen a world where Money is key measurement of how society is doing.
By inconvenience, I assume you mean the magnitude of their bank account and/or stock portfolio…
