I know this is the inevitable and cliche pushback, but it never seems to be grappled with so it remains worth pointing out: none of the three things you mentioned are anywhere close to monopolies. There are lots of social networks (Twitter and TikTok are extremely successful, among others), lots of ways to search the internet, and lots of ways to shop online. The analogy with the railroads simply is not apt, their mo…
I think we need to be clearer by what "product" means when it comes to monopolies in the Information Age. In the Industrial Age, you had a monopoly on paperclips if the only way to buy a paperclips was through your company. But paperclips themselves are commodity-like: there are billions of them out there and each is more or less interchangeable with the others. Information products are not like paperclips. Each piec…
A piece of information is not unique. You and I can both know that 2+2=4. We probably both know what the president looks like.
That's the complication.
There's nothing preventing you and your family from being part of multiple social networks. There's nothing stopping a site from being listed in both Google and Bing. None of that information is necessarily unique.
Here's the real rub. Whether or not your friends are on multiple social media networks isn't controlled by Facebook; it's controlled by your friends.
I think it's going to be really hard to argue that Facebook has a monopoly because people use them and refuse to create accounts elsewhere. Facebook isn't taking away your choice to connect with your friends, your friends are. The accounts are free, and Facebook isn't going to ban you for having a Mastodon account.
I still think we need a more open environment. I just think we need a new concept for what's happening instead of trying to logically torture the situation to fit a heavily abstracted notion of a monopoly. And then we need to ban that concept.
