For Bamboo, I immediately think of Jenkins, although it's showing its age now.
For Confluence, I think of Media Wiki.
For BitBucket, I think of self-hosted GitLab.
Not sure about Jira or Service Desk, though.
I'd appreciate any better suggestions.
The thing Atlassian had going for them is that we could get our non-technical people to use their stuff, understand it, and even customize it themselves to meet their needs. I'm not looking forward to trying to bend some other issue-tracking system to do it, so I'm guessing we'll pony up for the DC-class charges (for the few years they continue offering that option) and see if a competitor emerges.

Confluence is probably the hardest one. You could use any wiki software but the new "live-editing" stuff (Google Docs style) is pretty good for productivity. Hard to find an on-prem equivalent. Confluence's integration with Jira is hard to compare too.
I always go the impression that GitLab was doing excellent in code related workloads but sub-par in issue and test record tracking.
Tuleap shines with very advanced tracking capabilities and, most important, empower end users to manage it. Unlike Jira, you don't depend on a central admin to tweak you configuration, everything is at hand.
Git & CI capabilities are built-in but if you prefer gitlab for that, you will have soon an integration between the 2 tools. It's part of the next delivery [2] due mid november.

- federated file sharing
- real-time collaboration (e.g. via OnlyOffice or Collabora)
- calendars
- video conferencing
- kanban
- webmail
- webhooks and push notifications
- discussions and mailing lists via Discourse
- Matrix/Element, Mattermost, or Rocket.Chat, IRC, and Slack integration
- Github and GitLab integration
- help desk via Zammand
Nextcloud is not without shortcomings. But, it's strengths are being federated, open-source, and integrated with an exosystem of open-source community and productivity tools.
One additional note, our small cooperative uses a managed version of Nextcloud from Web Hosting. The cost starts at $35/month for fully managed or $7/month to update Nextcloud manually via the settings page (which is surprisingly simple). The Web Hosting Web page and sign-up process are slightly klunky, but their customer care has been excellent in my experience.
Your FAQ also says to "Contact [You]" regarding on-prem instead of pointing to the GitHub, which imo conceals the fact that you can build and run it without a restrictive license.
Its fast, lightweight and MIT licensed.
Rather opinionated in design and structure though.

Some big organizations are using it (like Facebook, Wikimedia Foundation, Mozilla)
Does anyone have a first hand experience working with it comparing to standard Atlassian stack?
(It's my start-up.)
Having used and looked inside both Media Wiki and its enterprise fork BlueSpice, I can't really recommend either if you need anything more serious than just "minimum viable wiki features".
A few years back we temporarily switched from using Confluence to Xwiki, which worked okay for a while, but then different small and medium issues kept adding up until we had to go back to Confluence and swallow the increased price (sixfold in a span of 3 or so years). This was with Xwiki 8 though, the current version 12 might have improved things, I should try it again really.
