If you block adobe.com entirely, some legitimate paid apps may fail to load essential UI resources (fonts, help menus). Instead, block only licensing and telemetry subdomains. While Adobe frequently changes and rotates their server
The hosts file remains a fundamental, operating system-level mechanism for domain name resolution prior to querying external DNS servers. Within software management communities, maintaining a curated block list of Adobe-related domains is a common practice intended to prevent license validation, disable feature gating (e.g., Adobe Firefly), and block telemetry data transmission. This paper analyzes the structure, implementation, and effectiveness of the top community-sourced Adobe hosts block lists.
