It wasn't much of feud, considering the majority of genre fans were on his side..... the Dixie Chicks careers were self-tanked so bad by their flippant dismissal of who their fans were, they might as well have stood on an IED. It was gone overnight. Even I knew at the time they were doomed, and I was not a fan of Red White and Blue because I didn't like the overall turn towards essentially the Osama diss track phenomenon. I stopped listening to pop country at that point because I just wanted to listen to some nice "neutral" music at that time, considering all that was going on in the world, not pick a side and get constant reminders of the reality I was trying to escape. (Remarkably similar to today, but without the internet in your pocket, it was easier to ignore most of the time)
Keith not only is still arguably popular today, there's no doubt his legacy will be positive and long lasting, a pre-social media slap-fight with a now-dead group will hardly be recalled and if it is, it will be remembered as him winning. His 90's stuff gets re-spun on the "flashback" segment of the country station's programing lineup all the time, while the DCs are persona non gratia and have failed to reinvent themselves in a meaningful way after telling all their fans to kiss their asses if they didn't like mid-00's Bush-bashing proto-progressivism. It wasn't THEIR job to make the fans happy, it was the FANS job to do better..... they were kind of patient zero when it came to modern performance artist sensibilities in that regard.
Can't recall the last time I heard Wide Open Spaces being played anywhere. It used to be just as ubiquitous on the truck radio as anything else back in the day. And I remember what was on in 93' because that's the year I got my license and one of the first things I had to do upon getting my first hand-me-down truck was replace the AM-band-only radio so I could get 98.1 , the local country station. (it was a 78' what'd you expect?)
But, you know, who has time for research or consulting first-hand sources like me when you're soopah-smaht like Bob and clearly, a performer's discography doesn't extend back prior to when you first heard of them?
