I don’t know about established companies pivoting but new operations/projects don’t seem to default to Jira like they did previously. In my very non-scientific sample size, I’ve noticed a shift in the last 3-6 months

What is everyone shifting to, and at what scale? I can see moving to breaking down tasks in separate markdown docs for a small(ish) startup, but working at a company of more then say 1k or so requires a bit more infrastructure to deal with the cross cutting concerns (compliance/legal, pm's, leadership, etc). I'm at a reasonably sized F500 and Jira is the default, despite how much all of us despise it, mainly because it ticks all of the boxes for aforementioned areas.
