Bolded: If I remember right, the united states and european union imposed sanctions against russia and banned them from the SWIFT financial network. The only option available to russia (and nations under sanctions) was to find ways to become more independent and operate outside SWIFT utilizing financial networks which are denominated in something other than the US dollar. In a way, one might say that russia was banned from using the dollar under sanctions, and so they sought alternatives which is a bit different from blaming Putin for everything.

The major push for abandoning the us dollar comes from china btw. Over the last year china has moved to denominate its oil transactions in the yuan (china's native currency). China has leveraged its political and economic influence towards forcing saudi arabia and russia to likewise sell china oil in their native yuan currency. I don't know how Vladimir Putin deserves the blame for any of this but alas he looks innocent here.

I think may's US economic metrics will be critical in determining whether we'll soon see a recession as well as how severe it may be. Its nice to think that "only corporations will go down with the ship" if another crisis happens. The sad truth is it would have a negative effect on everyone.
