Are there any other examples where an incumbent lowering prices in response to competition was a positive sign for the incumbent? I'm also trying to unpack "legitimize" to something more concrete...

Or perhaps it's simply AWS flinching and consequently customers perceive Cloudflare as more legitimate and move more business there?
