I don't know, DC comics has done a pretty decent job staying afloat.

Yeah, but DC has always used reboots to bring some measure of sanity to their chaos. The EU hasn't done anything like that yet; they just keep churning shit out, stamping it all with a CANON mark, coming up with contrived retcons whenever something new contradicts earlier material in a vain attempt to make it all work.
