You installed, tried and subscribe to Siphon's Add-on servers when providing your email address to gain access to them. Notifications about other Apps or Add-ons the developer is working or supports is a common courtesy for those that my be interested and never knew about the other projects the Add-on developer is working on. If you don't want to receive unwanted emails never use your real email address when subscribing to any type of online services always use a temp email service if you can find a good one. Also, the ranting was unnecessary you could simply just select to 'unsubscribe from list' at the bottom of the email you received.
