Big tech can also support lots of junior developers, because they can scale their teams. They don't need to operate lean, they could have one dev per Class if they wanted, so even if the code base is a big mess, they can just throw more brute force at it by having two, three, four teams, or as many as needed to work on the code base and break it down into smaller services each team can focus on.
