While I agree that "corporate America" is problematic, the lessons from Voyager are not really applicable. For starters, it was designed to take advantage of something that predictably happens every couple of hundred years. Very few corporations last that long. Then there is the element of predictability. The solar system pretty much works like clockwork. You can predict simple things, like the orbits of major bodies, centuries in advance with a great degree of accuracy.

Compare that to the tech industry. IBM itself can trace it's origins back to a data processing company about 140 years ago. They probably had the most natural evolution into a modern tech company because of those origins. Yet noone at the original mechanical tabulator company could have predicted what IBM would be producing 70 years later, nevermind a century later. Nintendo is roughly the same ago and is more-or-less doing the same sort of thing (gaming) but has gone from low-tech to high-tech so their path was not predictable. Yet those are abnormalities. Almost anything that old is an institution of some form (e.g. government or education). Perhaps the closest thing we had to predictable was Moore's Law, but that wasn't a pure law in the physics sense. It was reliable enough to build an industry upon for many decades, but it could have failed much earlier than it did due to hurdles in technological developments.

The other thing about Voyager is that its intrinsic value grew with time. While we could develop a mission that could go as far as it did faster, and have better instruments to conduct research, it would take decades to build the probe and get there. It also makes sense to support it to get what little data it can return to us because it would help us develop better missions when we do decide to go that route.
