But that's the catch, company breakups are extremely hard to perform especially when you're talking about such a giant company being tackled by an organization that only has ~400m in funding. Especially when they can point to the other giant companies as defense against claims of monopolist behavior. See Google using Microsoft, Apple, and Amazon as a reason for why their ad business should not be broken up in the January lawsuit.

On top of all this, a lot of users don't care, which is a problem itself, but also leads to an even harder time trying to navigate a company breakup. The convenience is too great for them, and it's too easy for the above noted companies (alongside other giants like Walmart) to shift public opinion.
