According to this 2013 BBC article:
My conclusions? He didn't singlehandedly rescue the Canadians from the worst of the global financial crisis - he didn't really need to. But boy, did he win over the press.
This is a man who established a reputation as a "working-class hero" to many Canadians, despite having spent 13 years at Goldman Sachs.
I don't know anything about him, but given the current economic climate, I'm skeptical. Hopefully he's good for Canada, and can deal with the economic catastrophe Trump is creating.
It was removed because Google did away with manifest v2 for browser extensions, and uBlock Origin worked almost entirely from a feature provided in manifest v2. So it was removed because it can no longer work on chromium devices, unless the browser manually adds back in support for it. Firefox has chosen to continue to support manifest v2, so the original uBlock origin is still available. uBlock lite is still available in the chrome store, and uses the new manifest v3. It is more limited in it's capability, but should be able to get the most obtrusive stuff. The lite version is definitely not nearly as powerful as the original.
On a side note, it seems to me like the link still works for now. Idk how much longer that will last.
