If it requires nothing more than a click to cancel, it seems like you'd be happier in life if you viewed such a thing as merely a two-step process (signup, get what you need, cancel immediately) rather than a serious commitment to spend $5 a month for the rest of your life. Unfortunately, everyone in business is now required to do this 'wishful thinking' that people will commit to everything. I laugh sometimes at items that Amazon hilariously suggests that I "Subscribe & Save" to!
When signup is one click, and cancellation requires a phone call... then I'm right there with you with the pitchforks!
