You are actually showing the third-party scripts from patreon.com. not from the /e/ website itself. Check the website address in your browser.
/e/ just uses patreon as a financing platform as they process payments and handle all the recurring donation subscriptions. /e/ has no influence in what patreon chooses to embed in their site as they are completely independent from /e/. They are a seperate company like Paypal etc.
Howevery, I partly agree with your point. Processing payments with a company which obviously does not care about their user’s privacy like patreon does not really comply with /e/'s general mission and values. Maybe it would be a good idea to choose a donation provider like liberapay.com over patreon?
