For all we know it will lose users for going "mainstream". And advertisers for having to tell the Truth about their numbers.
If not why the rhetoric?
Because "rhetoric" (or less euphemistic: lies) is the best argument the climate change deniers ever had.
it's existence is only political to people who's politics is denial of objective reality.
No, that is backward. They don't make it political because they deny reality. They deny reality because it's political.
And it's political on both sides. The best-known spokesperson for addressing climate change is not a scientist but a partisan politician: Al Gore.
The second best known is Greta Thunberg, who intermixes support for Hamas with climate change advocacy.
Gee, is it because any scientist who even dares say something about the dangers of climate change is accused of being "political", and that's just the least that criminal propagandist will claim about them.
Neutrinos have bad breadth.
