WikiSuite | Constructive Cost Model COCOMO

As of 2019, WikiSuite's cost to develop is between 50 and 100 million $USD.

Really?

Yes. If you tried to re-code WikiSuite using proprietary models. Ref: https://en.wikipedia.org/wiki/COCOMO

How can it be free and who paid for this?

Like Wikipedia, GNU/Linux and Firefox, WikiSuite is the result of massive collaboration.

How do you arrive to 50-100 million $USD? Are you including the cost of GNU/Linux?

Nope. Just the Linux Kernel would cost billions to redevelop

The WikiSuite-specific code (mostly ClearOS installers):
0.2 M: https://www.openhub.net/p/wikisuite/estimated_cost
This is intentionally as small as possible since we focus on upstreaming code to the various Software Components

The main software components:

Tiki Wiki CMS Groupware

Plus 125 external dependencies, managed by Composer
1.2M downloads
350 code committers
68 000 commits
x wiki page edits
y printed pages on doc.tiki.org

Ok, but I am not going to use all the features

That is true of all feature-rich software. But the economics don't make it feasible to build software just for your needs. Community Free / Libre / Open Source software will necessarily want to cater to a wider community and get more users and contributors.
