I suppose people get automatically annoyed because who the owner of Slack is. It is reasonable to assume bad practices if the company is too large to care, have multiple prior bad incidents etc - that is why people automatically assume guilt with companies like Oracle, Comcast, Salesforce etc etc. If the company in question was a small 50 person outfit or unknown, people might assume it was an honest mistake or at least give benefit of the doubt.

Not saying it is right or wrong - just pointing out that people's patience is in short supply when it comes to mega corps, simply because of their very bad track records...
