Anthropic is a US company, so it is lobbying the US to enact regulations to serve both its interests and the interest of safety. What else should it be doing? I imagine Anthropic (or at least many of the people who work there) are fully aware that USA is the bad guy right now, but that doesn't change what levers they have and do not have available.
it's easy to forget. openai and anthropic, were at one time more like foundation-style nonprofits interested in open source research. the idea was to benefit humanity, not US interests and not company interests.
over time they became closed source, for profit, US military contractors, and the clients of expensive political lobbyists.
anthropic once said it was their identity to stop scaling before the current model capability; they rewrote the responsible scaling policy so that they could continue scaling. openai said in its founding document that it would be unconstrained by return on investment; it restructed into the for profit setup. deepmind signed documents when it was aquired by google stating that its ai would not be used for military purposes; they rewrote these commitments to sell gemini to the us military. it wasn't like this!
it did not have to be this way. even though everyone will IPO and become yet more accountable to shareholders, there is still time.
