LWN, the Linux and open-source news site that has run on a reader-subscription model since 2002, announced its first price increase since early 2022. The new monthly rates rise by about 20%, mirroring US consumer-price inflation over that period, moving to $6, $11, $19 and $55 across its four subscriber tiers. Existing prepaid subscriptions remain valid until they expire, and current monthly subscribers keep the old rate for six more months.
