Whining about a for-profit product no longer having a free-tier is odd to me. Either be fine paying for the service (nothing wrong with that) or pickup software that is free; I for instance personally use org-mode and Emacs heavily for all of my personal information management.
I also do not understand the sentiment that every product acquired will slowly begin to suck; that happens for some products sure but the converse is also the case.
To be fair to Atlassian, I used to hate Jira a lot but in recent years had to use it for work and it quickly grew on me; they are putting effort into improving their services / products, modernizing their software development processes and technologies, and delivering updates to their software on a regular basis.
If you're going to contribute here, please be more constructive or detailed. Why not talk about your ideas for a project that is free that anybody could install on their servers that does what Trello does if you do not like that they may begin charging for Trello?
Edit: fixed unintended mistake in the company name

PS: Here's a bonus issue that took 10 years to resolve (renaming users!): https://jira.atlassian.com/browse/JRA-1549
Not as old, only 5 years. Yet this is blocking my switch to a new CI server (GoCD) and makes building pull requests in general a pain.
They don't say if it will stay free or not.
Somehow the only good things I heared about them came from people who made their money by building stuff they wanted to sell on the Atlassian platform. People less biased always choose alternatives.
I can't say much about them myself. I only used Bitbucket, because of the free private repos. Their UIs are pretty mediocre, but I use it via Git cli, so it doesn't matter much for me.
After Atlassian bought them:
* The service I paid £5 a month for became free
* The stability issues started to improve in a dramatic fashion
Today Stash is a great product (IMO), and BitBucket has really improved from having great Jira integration.
I was actually sad because I couldn't justify paying for the premium features (multi-person private repos) in the same way, because it was nothing I needed. It was the best £5 subscription I ever had :)
I generally prefer Bitbucket over Github now (was a paid subscriber of Github). I basically use Bitbucket now for private repos and Github for my public repos, since Github does seem to be the place to put open source projects.
If my Bitbucket needs ever reach the point of having to pay for a subscription, I'll do it gladly.
JIRA has its quirks but it's very flexible and customisable. Its UX is also quite ok for such a complex piece of software. Keep in mind they're competing with stuff like SharePoint and downright UX atrocities such as HP ALM.
Confluence is among the best enterprise wikis targeting end users (i.e. users not familiar with Markdown), too.
We use Jira since the early days, and are quite pleased with them.
So far, all the other systems I have used were all worse than Jira.
