"If this case is eventually decided in favor of hiQ, scrapers can no longer be blocked."

If the case is decided in favour of hiQ, then, absent an injunction, what would prevent a website from blocking a scraper? Maybe the website could still block unless and until the scraper gets her lawyers to file an injunction.

Another interpretation is that if hiQ wins, then in the 9th Circuit's jurisdiction websites serving public information they neither own nor exclusively license may no longer try to to use the CFAA and/or copyright law to threaten scrapers.
