Could you be more specific? AFAIK there are no ads in Google Talk/Hangouts, Calendar and Contacts. Google is known for making the vast majority of its money from ads, but definitely not for putting ads in all of their products.
Even if they did show add in these products, how does that relate to supporting standards as alternative means of accessing your data? Like in Gmail, which shows ads in the web interface but also supports POP and IMAP.
