The problem is the damage was obvious in 2014, and it took until 2025 for us to do anything about it. In the tech cycle, that reaction time is way, way too slow. Honestly, the biggest part of the problem is not when they started investigating, it's how long they allowed these companies to abuse the process.
This case started in 2020. What companies like Apple and Google have done in most of these cases has been to abuse the court's willingness to provide extensions to create an incredible amount of delay. One of the tactics they use both here and in the EU is to say they need more time, and more time, and more time, and then on the very last day of the last extension just say "nah, we don't think we're doing anything wrong". They didn't need the extensions, they were just wasting time. Because the amount of money they make on the status quo is worth drawing out as long as possible.
If anything, I think the biggest reform would be to say that large companies do not get to ask for extensions on court deadlines. They have literally billions of dollars, hundreds of lawyers, there is no reason they cannot manage to get what they need to do done on schedule. Asking for more time should be viewed as bad faith.
