No it doesn't. It really doesn't.
What it comes down to is security/privacy versus convenience. You want something like Whatsapp, FB messenger or iMessage because "it just works™" is cross platform and the masses are on it. It configures itself, and it just works. Since you're not paying for it why in the name of any god would you expect them to put you and your privacy/security as a priority? Even Signal Private Messaging app which uses fantastic encryption uses their servers, so there has to be a degree of trust there too.
If you want secure, private, electronic communications with NO 600 page user agreement that basically says they can do what they want with your data, then you need to do the work yourself. Start using OpenPGP encryption on emails. It's about the only way for true security and privacy.
But, of course, nobody ever will. Because it involves effort. People want top tier services for free then complain when the people giving out the service do things to monetise the platform.
