Missing key feature such as centralized mgmt, centralized billing, data retention policies, ...

Ads take up over 25% of the usable space.

On the other hand, if you lose your copy of one of your conversations, you may be able to get a copy of it from your government with a little bit of luck and a public records request.

Though it might limit the amount of unwanted rude people in your chat, it does limit the functionality in some games, where chatting with randoms would be beneficial.

The overall voice quality if very bad. The voice is kinda high-pitched and it adds some background noice to everyone, even when they're using a noice-canceler

I have to go back to my desktop to remember to invite my friends to the voice chat. Incredibly annoying.
