alt Hacker NewsSlightly tangential thought:
My belief is: legislation needs to either make it just as hard to merge two companies as it is to unmerge them, or make it just as easy to unmerge two companies as it is to merge them.
It's insane to me that for how often companies merge and cause competition issues, we effectively never see the opposite happen. I know there's a ceremonial approval for merging two companies (at least in the US), but it's just impossible to undo or prevent the damage.

You're basically advocating for unscrambling the omelet to be easier. Should be obvious why it's harder to unmix than it is to mix.

There's no such thing. Let's stick to software since it's what HN knows best, but it's a universal truth.
Merging two companies: you take the two sides and they keep running. You probably need some extra accounting work to make sure the mandatory reports from each side get combined, but that's all you have to do.
Splitting two companies: oof. If you split ChildCo out of ParentCo:
* You need to hire all the roles that weren't part of that organization before (HR, legal, compliance, etc.)
* You need to register this new entity in all the countries it operates and/or has employees in
* Technologically it's somewhere between messy and impossible. Now you no longer have Google's build stack or monorepo. You have to rewrite everything. You can't just move some VMs to a cloud provider of choice
I don't necessarily disagree, but in practice it's never as easy. Combing ingredients for a cake is always easier than separating them back out. Getting married is easier than getting divorced. It almost feels like some kind of fundamental law.
My experience is that "split" companies are often split only at the superficial financial level and the behind-the-scenes engineering systems are never actually decoupled, you just have a services agreement where the new company pays the old company to continue providing software. Or vice versa. It's usually pretty ugly and expensive and not the clean win for competition you are thinking about.
We stopped this in the 1950s with a 90% federal income tax bracket. CEOs could not make more thab the equivalent of 5mil a year in 2026 dollars.
No CEO wanted to merge when it would turn two 5mil a year jobs into one 5mil a year job. Cutting taxes on the rich enabled profiteering by CEOs.
This point of view has more to do with your information diet than it does with reality. Companies un-merge and spin out all the time, for many reasons. Mergers and acquisitions are more interesting because they are often associated with a growth story. We like success.
Aswath Damodaran, who teaches corporate finance at NYU Stern, has a bunch of great talks and content about this where he discusses how companies should act their age. When older companies that are no longer paying dividends are moving into a divestiture phase, they restructure and split up. What we are seeing with some of these big tech companies is that they are transitioning from an exciting growth story into an extractive dividend story in a way that's becoming harmful to consumers. That's why we're talking about breaking them up, and thats the line their management will have to walk if they want to maximize the value of the firm to shareholders through the decline.
