Across many different software ecosystems: .NET, JavaScript, Ruby, Python, databases, et al - there's been waves of popular open source projects re-licensing from permissive, business-favor license structures such as Apache 2.0 or MIT to mere "source-available" license such as the BSL.

Redis, Terraform, IdentityServer, FluentAssertions, and more - to name a few.

In this talk we address the following:

* Why does this keep happening?
* What can we do when a project re-licenses?
* What do we need to do to help keep OSS "free" as in "free beer?"

Target audience is everyone involved in software product delivery. I've not presented on this publicly at a conference before but I have written numerous blog posts about it, such as: https://aaronstannard.com/relicense-or-die/
