Anthropic is absolutely taken seriously in workplaces, what are you even talking about?
No serious business uses Pro or Max, they are all on Anthropic API billing.
In fact with this move it is plainly obvious that Anthropic is moving compute from prosumers towards enterprise.
But the API is incredibly expensive. I calculated that I would have spent 3000 EUR the last month, a lot more than the 100 I pay now.
I work for a "very serious" company with many billions of dollars of revenue. All our SWEs have max subscriptions.
I know of a very serious business that deployed Max to all of their developers. API pricing, from what I see, can become more expensive than just hiring another dev.
