They won't. They might notice shrinking revenues if some of their customers were VC-funded startups or other people in that ecosystem, but the decline of funding is at worst irrelevant and at best good for them. (Less funding means less competition.)

But then, since it's irrelevant, bootstrappers have little incentive to comment here, other than a few folks for whom HN has become a habit. From where I sit the bootstrap startup world is actually significantly larger than the VC world, but the incentives are different: it is not to a bootstrapper's advantage to publish what they're doing to people other than their customers.
