Anthropic isn't backed into a corner. They have plenty of enterprise subscriptions. Individual user experience (especially billing) is suffering because it's not a priority in comparison. If they were as desperate as you described, they would try selling access to mythos.

The fact that they are adding code specifically to charge individual consumers more reeks of desperation. This isn't "individual users are suffering because they're lower priority and neglected", this is "individual users are being actively squeezed because Anthropic is desperate for every penny it can get".
