What are some example of crippleware?

Crippleware refers to software that is intentionally limited in functionality until a user pays for an upgrade. Examples include free versions of antivirus programs that restrict certain features like real-time scanning or malware removal, and trial versions of productivity software that limit usage time or available tools. Some Video Games also employ crippleware by allowing access to only a few levels or features until the full version is purchased. These limitations encourage users to upgrade for a complete experience.
