"The guild" is absolutely free to go seek other vendors if Anthropic declines to sell to them.
> Additionally, even if there is a guild - no guild ever let a vendor pick and choose what [the guild's] capabilities were, that would be insanely dumb.
The analog you're trying to describe doesn't exist, which is Anthropic saying nobody else can make and sell an offensive model to "the guild."
Against their will.
Historically that is a major reason why guilds existed, actually.
It’s an extremely modern invention that corps have these type of power over their customers.
Here's your original claim: "no guild ever let a vendor pick and choose what their capabilities were"
A carpenter's guild can prevent other people from doing carpentry. That is not what's being discussed here.
A carpenter's guild cannot force a horseshoe maker to begin making hammers. That is what's being discussed.
Your initial claim was analogous to "never before has a horseshoe maker been able to decline making hammers when the carpenter's guild needed hammers"
Obviously they have and any other state of affairs would be flatly insane.
