What exactly did "Disney" mean? Plundering public domain stories? Gobbling up IPs to make movies out of? And this was all done during Walt's lifetime and continuing thereafter.
Below are Disney animations listing IPs that were public domain (and therefore, not an original Disney IP) and bought/licensed. These are stories that were never originally created by Walt, his staff, or the company after his death. Disney (with and without Walt) has always been an aesthetivore, eating up other people's creativity. If you think there is something uniquely Disney that precludes bought-up IPs, then the thing that is uniquely Disney is their salesmanship making you think that.
And I haven't even touched their live action "work" such as the quintessential Disney property, Mary Poppins... which isn't Disney.
