I abandoned slack the moment they dropped web-based client support. Deployed different client on my own infra, and never looked back. Nobody even noticed.
HN added this comment based on my submission. I simply filled out the form that was provided for making new submissions. Sounds like if users don’t want comments like this that HN should change their submission form.
