**Claim.** Existing decentralized filesharing networks cannot guarantee the availability of unpopular files such as personal files, whereas centralized cloud services guarantee availability for a fee.

**Type.** failure  **Support.** argued

**Holds when.**

- applies to filesharing networks without an incentive design for storing unpopular data

**Source quote.**

> One problem with most existing decentralized filesharing networks is that unpop- ular files (such as your personal files) are not guaranteed to be available, unlike cen- tralized cloud computing services which guarantee availability for a fee.
