People are _way_ too trusting of Slack and similar services. You could run your own IRC or Mattermost server accessible only in your LAN or over VPN and this would be fairly safe. Heck, even SSL-only with cranked up SSL options would be fairly safe. Instead, people ship all their data off to a 3rd party company, often letting that 3rd party have control over their servers and such. Their customer data, their payment data, even code exec on all their servers is exposed and out of their control. It's insanity, I can't believe people have so little regard for security. Especially with a 3rd party company with a less-than-great security record.
