I think the "Mythos" name is genius. The people at Anthropic make a bunch of claims and the public is expected to just believe them without any possibility of testing those claims or reproducing those results, and since so many people are invested in this saviour for the Global economy, or in the industry in general, or in hype to feed their engagement-based income sources, then there is faith to spare.

Meanwhile this mythical beast wasn't able to prevent the Bun vulnerability that exposed their code, let alone precluding the need to acquire that IP in the first place for presumably hundreds of millions of $$$, instead of coding a better replacement or a solution of its own.

What is real and measurable is that subscription plan users are getting a much degraded service for the same money through both open and hidden policies, while Anthropic moves compute to serve off-the-counter customers. The same people who come with the most obvious and brazen lies to dismiss the clear degradation of their service also come with this "security" justification for a move that looks just like good old market segmentation which would perfectly fit the strong symptoms that they cannot afford to offer tokens at a competitive price in this market.
