I've heard about "landmark" cases against these companies over and over again for the last decade. There seems to be at least one every couple of years. And yet literally nothing has ever happened or changed.

Since these are civil lawsuits, it just takes more people coming forward to sue. There are plenty of cases where a jury found a defendant liable for damages only for the defendant to continue the bad behavior and subsequent juries awarding ever-increasing and compounding punitive damages. Big Tobacco and Purdue Pharma (went bankrupt) are examples of this pattern. Monsanto was famously hit hard with massive "repeater" damages after they continued selling and marketing Roundup despite prior judgements.

The exact same can happen to Big Tech. The goal is to get them to stop the bad behavior now.

I feel the same way. They're just going to appeal the case until they find a layer of the legal system where they have leverage.
