For developers that might be true that voice/video call is not happening often but I don't think that other business functions would share the same perspective. The ability to call, video conference and easily share images and docs is an important need for collaboration in Design, Marketing, Product Management and as a PM I often had to share screenshots back with engineers to illustrate what I'm talking about. Then, from my experience large orgs do not want to have multiple chat systems that compete with each other internally, so they'll take the one that offer more versatility while being also easy to use.

Disclaimer: I'm an ex-Atlassian (Product Manager) and my feedback is genuine, coming from experience. I'm also super happy to see my ex-co-workers getting Stride out but my opinion is not a Marketing plot. Software now requires the collaboration of many different roles, many of them who would prefer Slack/Stride over IRC.
