It makes absolutely no sense to apply the lessons from one into the other.
Sears was hardly horizontal. It was also Allstate insurance and Discover credit cards, among other things.
Each of these units were then given access to an internal "market" and directed to compete with each other for funding.
The idea was likely to try and improve efficiency... But what ended up happening is siloing increased, BUs started infighting for a dwindling set of resources (beyond normal politics you'd expect at an organization that size; actively trying to fuck each other over), and cohesion decreased.
It's often pointed to as one of the reasons for their decline, and worked out so badly that it's commonly believed their owner (who also owns the company holding their debt and stands to immensely profit if they go bankrupt) desired this outcome... to the point that he got sued a few years ago by investors over the conflict of interest and, let's say "creative" organizational decisions.
basically "coffee is for closers... and if you don't sell you're fired" as a large scale corporate policy.
The part about no overlaps already made it impossible for them to compete. The only "competition" they had was in the sense of TV gameshow competition where candidates do worthless tasks, judged by some arbitrary rules.
That has absolutely no similarity to how Samsung is organized.
Anecdote: Even before Amazon officially killed Chime, everyone at least on the AWS side was moving to officially supported Slack.
But removing the market competition is a breeding ground for inefficiency. So there's a balance there, and huge conglomerates tying their divisions together serves only to make the competitive ones die by the need to use the services of the inefficient ones.
Don’t spend energy on undifferentiated heavy lifting. If you are Dropbox it makes sense to move away from S3 for instance.
Imagine a hosting company and a dns company, both with plenty of customers and capacity. The hosting company says... I'll host your DNS site, if you provide DNS to our hosting site. Drop in the bucket for each.
One year the DNS company decides it needs to show more revenue, so will begin charging the hosting company $1000/yr, and guess what the hosting company says the same. Instead, they each get mad and find $500/yr competitors. What was accomplished here?
Further, it just looks bad in many cases. Imagine if Amazon.com decided AWS was too expensive, and decided to move their stuff off to say, Azure only. That wouldn't be a great look for AWS and in turn hurts...Amazon.
I do get your point, but there are a lot of... intangibles about being in a company together.
I know one project from Amazon got killed because their AWS bill was too high. Yeah AWS charges Amazon Retail for compute when they run on AWS hardware.

A bit like Toyota putting a GM engine in their car, because the Toyota engine division is too self-centered, focusing to much on efficiency.
Better yet, get a C8 corvette and gap all of the above for a far better value. You can get 20% off msrp on factory orders with C8 corvettes if you know where to look.
Or Toyota using a Subaru engine (Scion FRS, Toyota GT86)
They operate with tension. They're supposed to have unified strategic direction from the top, but individual subsidiaries are also expected to be profit centers that compete in the market.
Their point was that service levels are often not as stringently tracked, SLA's become internal money shuffling, but the company as a whole paid the price in lower output/profit. The internal partner being the default allows an amount of complacency, and if you shopped around for a comparable level of service to what's being provided, you can often find it for a better price.
That's hilarious, which phone is this?
My understanding is that the Exynos is inferior in a lot of ways, but also cheaper.

International models tended to use Samsung's Exynos processors, while the ones for the North American market used Snapdragons or whatever.
