Are you really trying to argue that companies which for example use Slack (or a similar service) are "not professional"?
Bringing anything else into the workplace is an unnecessary distraction from both the employee’s and employer’s standpoint. I go to work to have money deposited into my account twice a month and go home to spend time with my family and friends. The more time I spend at work spending energy not doing work either I will be less effective or spend more time away from family/friends/hobbies to be effective at work.
