SWE are paid that because the industry makes so much money off advertising, and it marks the market for everything else.

It's more business model than skillset, because RF engineering is, in many ways, so much more technically challenging.

People who care about pay should mostly be thinking about how their potential employers make money. Do they have fat variable margins? Is there volume? Do I have the opportunity to impact those margins in some way? If you do, there's a good chance you can make good money, regardless of the actual technical challenge at hand.

For a lot of RF engineering, the answers are generally no, at least enough such that the general market isn't getting set at a high clearing rate.
