I question the notion that JIRA is the only workable tool at large organizations. Many large organizations are full of small, relatively autonomous teams anyway, and those teams will benefit from a less bureaucratic tool.
Precisely, and larger orgs will most likely resort to yet another tool for higher level planning like ProductPlan. JIRA is left for product teams at the local scale.
But I guess if trello was enough, it means you don't really have bigger needs than having a list of tasks.
Stop assuming the thousands of companies which use Jira are stupid
