> my own example is the default home page for Canada. It's now exclusively sports and right-wing nuttery.
Can you give some concrete examples of this "right-wing nuttery" you mention?
I've heard other people in Canada make this claim, but whenever I visit the Reddit home page (without logging in; I don't have a Reddit account), I consistently see the opposite.
Right now, for example, two of the top five submissions I see are CBC and Toronto Star articles complaining about Ontario's Conservative government's policies. (For those who are unfamiliar with them, CBC and the Toronto Star are among the most left wing of Canada's mainstream media.)
Still in the top ten, there's an article complaining about how some corporate layoffs at Bell were conducted.
There's an anti-Trump article, a article about Biden cancelling some student loan debt, and a complaint about "the rich" (Musk, specifically) in the top fifteen.
Beyond that, there's a submission complaining about a landlord's behaviour, an article about urban planning in Vancouver, and the front page ends with a submission that's upset about some munitions company executive cutting down some trees in the US.
The rest are about sports, oddities, or otherwise don't seem to be political in nature.
I wouldn't consider any of the submissions I'm being shown to be obviously "right-wing" in any way. A number of them I'd consider to be centrist or neutral, if not left-of-centre. Several are overtly left wing.
