If I want to sign-up to a newsletter from a company I will usually find it either manually, or I subscribe to their RSS feed. In almost every case I visit a website, I do not want to subscribe to a newsletter. Therefore, it distracts from my goal. To draw a parallel: in almost every case I start up an Android application, I do not want to rate the Android application. I don't want to spend any time on either of such nonsense. In fact, from today on, I will rate applications on Android which ask me to rate them a bad rating just because I'm done with that spam. As for newsletters, if I want them, I will find them. Take for example Bruce Schneier's blog. You can find the newsletter without getting spammed about it. That's the correct way.
