But Trello was designed as the opposite of prevailing business tools at that time and part of that was that consumer use cases (e.g. college projects) were mentioned often in earlier examples, so it's hard to claim it as an example of a business tool migrating to consumer use.

Its taken a more business first approach since the atlassian acquisition for sure, but that wasn't always the exclusive focus.

It wasn't always the exclusive focus, but I think it was always the primary focus. After all, it came out of Fog Creek Software (now Glitch); given their product history, Trello would stand out as the only consumer-focused product they'd ever released, had they actually released it as one.

As I recall the original marketing (imperfectly, I'm sure, as it's been quite a while ago now), the pitch was focused around the concept of a project management tool without the usual overheads and complexities such tools tend to bring along, something you could just jump into and start using. "And you can even use it for stuff outside of work!" might've been there also, I don't doubt it, but I have to think it would've been secondary at best.

I agree, I'm not saying it's a 50/50 split. But I think consumers were at least considered in the design process for Trello, which is the not the case for Zoom.
