But that's not true. Again: Vendors absolutely pick and choose what their customers' capabilities are. Regardless of whether "the guild allows them to." Guilds can't force people to make or sell tools against their will – obviously.
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."
Guilds often very much did assert what people could and could not build - historically.
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.
