According to Google: > Cloaking refers to the practice of presenting different content or URLs to human users and search engines. Cloaking is considered a violation of Google's Webmaster Guidelines because it provides our users with different results than they expected. — https://developers.google.com/search/docs/advanced/guidelines/cloaking https://developers.google.com/search/docs/advanced/guideline... It’s clear that Google aren’t enforcing this rule thoroughly though. Edit: It’s possible that the allowed sites are using JSON-LD to avoid being classified as cloaking: > This page describes how to use schema.org JSON-LD to indicate paywalled content on your site with CreativeWork properties. This structured data helps Google differentiate paywalled content from the practice of cloaking, which violates our guidelines. — https://developers.google.com/search/docs/advanced/structured-data/paywalled-content https://developers.google.com/search/docs/advanced/structure...
