Borders Bookstore didn't want to cannibalize sales either and they don't exist anymore.
AFAIU Borders succumbed more to overexpansion and debt than legacy-protection.

Waldenbooks had been around since 1933. Books-A-Million dates to 1917. Borders to 1971. Barnes & Noble has been around in some form for ~150 years.
It wasn't overexpansion and debt that destroyed them all (yes, some are still standing in a straggling-on-zombie sort of way).
I'm aware the industry has seen shifts.
