Yes it's hypocritical to push customers to pay you more money with best practices for uptime when you yourself don't follow them and your choices to not follow them actually make the best practices you pushed your customers to pay you more money for not fully work.

Hey! Pay us more money so when us-east-1 goes down you're not down (actually you'll still go down because us-east-1 is a single point of failure even for our other regions).
