Anthropic、EU規制対応でClaudeに透かし導入、不正利用を警戒するユーザーが反発

Anthropic recently made the decision to watermark Claude’s outputs — inserting invisible code into the chatbot’s editorial text that marks it as AI-generated.

Anthropic rolled out this new policy to satisfy the EU AI Act’s Transparency Code, which now requires tech companies to label content that has been AI-generated or edited in a manner identifiable to computer systems. Yet while European regulators may be happy, some AI users are decidedly not.

One need look no further than Reddit to find evidence of brewing discontent, though other posters on the site are not in agreement. One of the more histrionic posts I came across was from a user named visionode, whose account is notably only three weeks old. According to visionode, the new watermarking system is a draconian conspiracy designed to victimize innocent chatbot users worldwide.

Visionode’s basic argument appears to be that, while savvy Claude users may be able hide evidence of their AI usage by paraphrasing or otherwise cleaning their outputs through other AI services, the average user of Claude will be caught.

“Who will get caught? You. The student who used Claude to reorganize a paragraph. The journalist who asked the AI to summarize a two-hundred-page transcript. The writer who had creative block and asked for synonyms. Those guys come out of the process with a digital tattoo on their forehead.”

Far be it from me to undermine visionode’s outrage, but those are not the best examples. A journalist asking AI to summarize a two-hundred-page transcript is not going to be bothered by a watermark attached to that summary, unless they are copying and pasting the summary verbatim into their article — which is plainly unethical and shouldn’t be happening.

It is equally unethical for a student who copies and pastes Claude’s output into an essay after asking it to “reorganize a paragraph.”

Other Redditors were also not particularly supportive of the poster’s outrage.

“Get a load of this guy,” one poster merely commented.

Another asked the OP to take “a deep breath.”

Visionode wasn’t the only one complaining. Another unhappy camper called the watermarks “unethical” and “disgusting” and argued that by using Claude, they had done the lion’s share of the work. In their view, the chatbot was merely a “tool” that had facilitated their arduous labor.

“I gave the instructions, context, decisions, and countless refinements, claude was the tool. If Claude starts watermarking the code or anything else it generates, what exactly is it claiming credit for?” the poster asked.

Again, other users dogpiled onto the critic.

“It’s not claiming credit though,” one user shot back. “It’s about being able to detect AI generated outputs because of the risks AI generated outputs can cause in various situations.”

“Bro couldn’t even complain about Claude without using Claude to write it,” another quipped.

Some critics have steered clear of the victimhood narrative and made slightly more nuanced arguments against Anthropic’s new policy.

For instance, one poster complained of a general hypocrisy in watermarking an editorial product that was, itself, generated by hoovering up other people’s work. “I think it’s a very sinister direction to take,” said the user. “I don’t use Claude to write anything but having an AI that watermarks your work is terrifyingly ironic given how many of the frontier models came by their training data.”

In general, however, users have tended to support the watermarking system as a sensible way to track material that was generated by algorithm. “There is literally no good argument for why this isn’t a good idea,” a user on another thread said. “The only reason you wouldn’t want this is to lie to people.”
