As it's currently being used, but that doesn't make it an inherent quality.
In WWII, fascists used tanks and planes. Does that make tanks and planes the tools of fascists? What about the Allies who used tanks and planes to defeat the fascists?
As things stand now, with the current governments, yes AI is being used by fascists, and when it inevitably crashes the economy the fascists in power will bail out the reach while leaving the poor to foot the bill.
But it's pretty unimaginative to assume that the fascist government can't or won't be replaced with one that will actually allow the billionaires to fail due to their own greed, and use the collective wealth from taxpayer funds to actually help the poor survive the economic disaster.
If you've already abandoned that possibility, then what's the point of anything? We might as well give up now if that's the case...
