Assuming the actual price for many user is closer to 1k USD/mth than to 200 USD/mth, and the actual price is closer to their target margin to be a viable business, they're practically subsidising usage after 200 USD/mth. Together with other AI-TECH doing the same, they fabricate a false sense of "AI is capable AND affordable", which imo is evil.
As the Wikipedia page calls out, predatory pricing is generally in the context of a dominant firm throwing their weight around to dominate the market. You could make this case against large incumbents like Microsoft and Google, but Anthropic is actually the upstart here.
In any case, all this depends on how you define the "market", and the entire market for AI-assisted coding is very nascent and fast-moving to make any reliable calls about dominance at this point.
