Microsoft Word has not claimed ownership in 40 years. Why would Anthropic do?
Because Anthropic are the type of strange people who think that language models have feelings.
They have said and tried some wild things already, like trying to get open weights effectively banned, which I believe they still think is in society's best interest (more that they think they know what's best for everyone)
I'm so curious if you're actually able to keep a straight face while typing that.
