The fact that this competing against yourself has worked in other industries isn't relevant because TTRPGs aren't other industries. A small niche hobbiest industry isn't luxury cars or sodas or Madden, and even though D&D is more popular than it has ever been it's still small potatoes compared to how much money other industries make.
Even if Hasbro can theoretically support multiple D&D editions at once (and that's iffy given how dire their financials have been lately), that doesn't mean it would work or make them more profitable, which is the only thing the company actuall cares about.
But more importantly, D&D has tried having multiple competing product lines before and it emphatically didn't work. The whole reason TSR went bankrupt is that they had all these competing D&D products that were by and large mutually exclusive--both D&D and AD&D, not to mention TSR's other non-D&D games and multiple mutually incompatible AD&D settings.
And on top of all that, we have retroclones for most past editions of D&D that are already that system but better. The only one we don't have one of those for is 4th Edition, because it would need a much more robust SRD.
