This all came about because this company had built a couple of hugely successful, and profitable, enterprise software products. So this company then decided to plow a ton of money into building out other products. The company was also pretty famous for having a high employee bar, and their college recruiting process was kind of legendary for attracting top CS and other tech grads.
However, this company discovered that building follow on successful products, even with lots of really smart people, is extremely difficult. As a not-perfect analogy, think of all the "one hit wonders" out there in the music industry. Beyond those one hit wonders, the vast majority of the rest are basically two hit wonders. Point being, once you've built a really successful product, even if you have tons of smart people, there is no guarantee that plowing money into another product will give you a positive ROI.
So this company realized this, and then saw there were a lot of other small-to-midsize software companies who were similar: they had one or two really successful products, but then were trying to use money from that to expand and grow into other areas, usually with little or no success. So this original company pivoted their business model: they went out to buy these "one hit wonder" software companies, immediately stopped any investment into other products, laid off as many people as possible and outsourced the operations and maintenance of the few successful products to low-cost locales (at the time, India and China) and then essentially just milked the subscription revenue until the product slowly petered out. That is, they weren't really investing in big new features in the product, but the product had a lot of existing customers who didn't (or couldn't) move off of it right away, so often they had at least a couple years of milking the existing revenue dry. I called it "the world's most successful and depressing business model".
My overall point in telling this story is that when you ask "Are you telling me that no one in such a big, wealthy company of clever engineers has any use for a bunch of talented people?", that often times the answer is "Correct!" People tend to underestimate how difficult it is to build successful products, even if you've already knocked one out of the park.
