Twitter/X clamps down on third-party viewers, Nitter gone

Nitter and Xcancel have been taken down following cease and desist notices, and a new Twitter viewer project appeared on HN the same day, with commenters noting the courage required to build a competitor immediately after watching others receive legal threats. The thread on the Twitter viewer explicitly references the C&D wave as a market opening.

The pattern is platform lockdown at the cost of audience. Multiple commenters across threads said they simply will not create X accounts, full stop. One described their GrapheneOS device slowly becoming a dumbphone as apps one by one block non-standard Android configurations. The PayPal-blocks-GrapheneOS thread is part of the same story: major platforms are using technical restrictions to enforce monoculture, and a segment of technically sophisticated users is walking away rather than complying.

For founders, the sub-story is that public social data is becoming harder to access without platform permission. Anyone building on social data pipelines from X should treat API access as a terminable dependency.
