Without real examples this just gives more reasons to load big libraries, such as jquery, from popular CDNs. Let’s take jquery for example; Speed - if everyone loaded jquery from the official CDN, considering the usage of jquery is high, you’re very likely to get a speed improvement. Faster website = happier customer (and happier search engine, which could mean more customers) That to me is enough. But... I do agree that if everyone uses that CDN and it gets compromised everyone is in trouble. That to me is enough reason not to use it. The article doesn’t do this one any justice IMO + it’s a personal decision because major CDNs don’t get compromised every day, so convenience might win here.
