This is depressing. Trello is a beloved software for a lot of people. It's sad that Trello decided to sell off to Atlassian. I can't believe the same company that makes Jira is going to run Trello. SourceTree is the only software that they make that doesn't suck.
I am far from expert when it comes to startups, their evaluations and acquisitions, but isn't >1million daily active users [1] not enough to make Trello a billion dollar unicorn? What Trello lacked to reach this? Is it all about the user count and it does not matter they pay or not or you have monetisation strategy or not?
