Your comment can be interpreted in two opposite ways, but it seems you meant that native apps allow the better tracking and ad delivery. While mobile apps are quite awful from this perspective, you must consider that the web is by far the most efficient platform for ad delivery and tracking. It's the web which has cookie pop-ups with dozens and dozens of companies that want to track you. It's the web which led to the development of ad blockers. It's the web where an app developer has full access to your data on their servers. It's the web where an app developer can at any time flip a switch and turn on telemetry, ads, etc.
