Atlassian is not known for great product experiences so I don't think it is at all unjustified to fear that a product people genuinely seem to love to use will turn into an uninspired mess. (disclaimer: I don't use Trello but I did use Jira and other Atlassian products for a brief period of time until I couldn't tolerate it anymore)
