Recently I found a bug in Slack, and I was communicating with their support over it. They asked me to check on the web in addition to the electron app. Now, the number of people who actually care enough to do this are a very small minority, but they are also very significant because they're happy to give Slack free QA. And as a member of this small minority that will reproduce a bug on multiple platforms and communicate back, I can say this seems pretty hostile to me and anyone else willing to pay money to do free QA for them.
