I think that one potential solution would be for the SCOTUS (who has made very wrong decisions in the past) to rule that third-party information is protected and requires a warrant just like entering your home. The decision to allow warrantless requests from businesses was a major error (or, maybe, malicious decision) in my view.

Step 2 is to ban such activity or rule that it is copyright infringement. And to maybe admit that scraping needs more guardrails and regulation.
