This is literally what all AI is right now. Anthropic has been paying companies to use its product to form that dependency and maybe they're not misaligned but there's no regulation in the US that'd in anyway deter them from purposefully misaligning their model.
Subsidizing a product to capture market share is very different from exploiting a national security attack vector.
Sorry, to clarify - this isn't just "offering it at a loss" Anthropic is directly paying PE firms to enroll their held companies in their services[1]. When it comes to a question of whether this is a national security attack vector I think there isn't a cut and dry argument and people could go either way but... private companies are not necessarily aligned with the US government even when contracted with the US government (see Starlink Ukraine shenanigans) and the steps the US government usually would take with highly critical infrastructure to ensure alignment haven't been taken - in my opinion at least, this is definitely a very subjective area.
