There's a sort of nihilism death spiral that can take over on this path. "Everything is made up and the lore don't matter!" Well, sure, but then there's no reason to invest in it, attach to it, no reason to elevate it, no reason to do better, endless excuses for phoning it in and messing with stuff because nothing matters anyway so who even cares.
When people stop caring about canon, why would Wizards. Your statement here is exactly correct. Why elevate the product, the art form, when it can just be mailed in, slapped with a D&D or Forgotten Realms logo, and called the next best thing?
