adonis just had a thread on roughly this topic. Maybe there's an economic case to be made for disallowing particular mergers (I haven't followed them and don't have an opinion either way), but the underlying animus toward these firms still strikes me as really strange.
I'm not sure "animus" is the appropriate word, but it's undeniable that certain companies have an astonishing amount of power within our country.
Anti-trust laws were put in place to prevent large companies from restricting competition through consolidation and cornering the market. It was in an age where this was done by cornering physical goods. It's hard to argue that a similar thing isn't being done today in terms of virtual goods, or data in our case. (And in the case of Amazon, vast data and AI is being used to corner physical markets - virtual marketplaces - by routing traffic through their stores, and for popular products, they actually start producing them themselves via suppliers from china, effectively cutting out suppliers in their marketplace.)
Only a handful of companies possess inordinate control over consumer data, and are using it to drive business to themselves at the expense of others. Amazon is doing this in many areas of their business. Google consumes our data to provide better services which allow them to get more data, and at some point it becomes a situation where barrier to entry to get good data and good AI just simply isn't possible because google has such a lead. Facebook...well, we know what facebook has done with personal data, targetted ads, tracking across platforms. And Apple...man, I love me some Apple, but they take a 30% cut of every app in the app store...which I can understand...and they're supposedly coming out with a new news app, aggregating sources across the world, for a flat subscription rate of like $10...$5 of which they'll keep for themselves. Why? Because they control the ecosystem where news is delivered.
From Google, to Apple, to Facebook, to Amazon...these guys are in nearly monopolistic control of the virtual world. We love their services, we're happy with the conveniences they offer, and yeah we get upset when the facebooks turn out to be free and loose with our info to the detriment of democracy, but step back and look at the ultimate power these companies have...all in the hands of a few people, with the ability to control what we see, what we watch, where we shop, groceries, apps, news. I mean...it's rather unbelievable the sheer amount of power these few companies have consolidated over the past few years.
The best explanation on why this isn't a bigger deal is that on the whole, they tend to make our lives easier, not harder...and facebook aside (maybe included) we're generally happy with the tradeoffs. The systemic risk still remains with so vast an amount of power consolidated in the hands of so few companies (and in truth, so few people making decisions within these few companies).
If the boards of these companies met regularly, and steered the course of their investments and what they wanted to see happen...they'd be undoubtedly the most powerful people on earth, in terms of their influence. Cross borders, cross continents...they can steer international events with their decisions, with their strategies.
All that said, I'd have to hear more discussion about the pros and cons of breaking them up, but certainly there's a HUGE risk there that few people are talking about.
