IF MONEY WERE NOT AN ISSUE, then perhaps yes - you could purchase the patents, and you could get the TSA to bend (it would take years and they would never do it in the middle of a Pandemic) and you could redevelop technology that other companies had invested years of research in. I can tell you that the budget for my company alone was measured in 20+ million range, and we were just one cog in the wheel and the only reason it was economical was because Disney subscribed to the service; didn't build it, or manage it and was just one (albeit an important one) of our customers.
Frankly it would be the most moronic business sense in the world for Disney spend spend north of 200+ million (AT LEAST what it would cost) and 3+ years bringing back a service that brought in no revenue and although did have some fringe benefits, would NEVER bring back that kind of return. And besides - as mentioned, it would take 3 years for them to do it and by that time people would have moved on.
To those claiming that stockholder value was a part of it, all I can tell you is that clearly you have never been involved in decisions of that sort. Our part was focused purely on the technology and feasibility. Other business units would be responsible to lowering prices based on their costs. DME may be a part in determining how much to charge because they have to pay back the business unit, but NO ONE is sitting there with a calculator and going "mousekeeping.... maintenance.... front desk.... DME. OH WAIT! THERE IS NO DME! CHA-CHING!". It just does not work that way. They add up their costs. They factor in their P&L, budgets, expenses and expected revenues and set a price that the market will bear. It's all very scientific.
But I get it. No one gets likes from speaking about reality. People want to believe that there are evil corporate execs rolling in gold coins making evil manicial laughs. Because that's the "in" thing.
