Anthropic's 'Watermark' Text Adulteration in Claude Is a Perversion of Writing

Anthropic is implementing a watermarking system for text generated or processed by Claude to comply with the European Union's AI Act. This technology makes subtle, imperceptible word choice changes that form detectable patterns. While Google, Meta, Microsoft, OpenAI, and Synthesia have also committed to EU transparency codes, the move has sparked backlash from Claude subscribers. Some users criticize the feature as text adulteration, fearing that even lightly edited AI-assisted content will be flagged.
