Open-source should remain open-source and as a MIT licensed project, EventFlow very much beleives in being open and free for everyone!

While there certainly is a problem regarding companies not providing any support (monetary nor PRs) to the open-source projects they use, what FluentAssertions has done is not the way. That simply causes too much uncertainty and too much work for everyone.

• Update ownership and license fluentassertions/fluentassertions#2943
• https://xceed.com/products/unit-testing/fluent-assertions/

Going forward, EventFlow would like to show its support via usage and downloads to the shouldly library instead.

So, you are up for it. Pick some tests and convert them to shouldly, it shouldn't be all or even all within a single project. As it is a rather big undertaking, I expect that both assertion libraries will exist in the codebase for some time.

As a side note, if you are a company and use EventFlow (or other open-source), really consider showing your support. Specifically, EventFlow has only received very few PRs from companies and no monetary support.
