I already sent SendGrid's sales department an email that I will boycott their company and recommend others do so as well moving forward. Where I work we were considering between SendGrid or Mandrill and this incident practically made our choice for us. We cannot and _will not_ support a company that backs[1] a person like this.

Want to tell us which company you work for so we can all avoid doing business with firms who makes decisions about which technology to choose based on whether or not they like the recent tweets of a company's employees on their personal twitter accounts?
I also don't see an issue with having non-technical attributes being part of the equation in the criteria for selecting a vendor. Price is clearly important, as can be a business' ethics; both are not technology related but can important depending on the circumstance.
Lastly Mandrill does seem like a slightly better product for the cost, but that of course might vary based on requirements.
