I'd hazard anthropic perceives their number 1 enemy as open weight models. If alternatives to their business exist (which is mainly coding tokens currently), they will get into a nasty fight and the nightmare of all tech companies - losing their monopoly. It threatens their ability to extract value, and could reduce their valuation to a tenth of what it was. They cannot make open weight models worse, so they're using lawfare to try and get them banned. And of course we previously know they attempted to block Chinese companies under the guise of national security by lobbying for restricting GPU sales.
