Their new focus on businesses integration is causing a lot of spam to end users from unsolicited business messages. There is no way to escape it.

Bought that something from someone a few years back and gave your phone number to them? Thanks. Now their hot deals messages reside right next to the messages from your family and friends.

I'm expecting good amount of market share loss once a good alternative is found that focuses purely on personal or group messaging and not on business spam.
