London Open Source Databases Meetup
Open Source Developer since 2005

Many other small projects and contributions
Philosophy - fix it and send it upstream
Recently developed FusionDB
Would like to Open Source it
Need to pay the bills
Need to ensure the future of FusionDB software
Originally we envisaged...
AGPLv3 - Gives us our "Open Source" and Freedom
Commercial License - Indemnity for companies that can't swallow AGPL
Would like to avoid "Open Core"
Things have changed...

From Apache to AGPL (26/03/2017)
... then to Apache + Commons Clause (03/04/18)

Trying to find a viable business model
Several squarely blaming large Cloud Vendors
Blaming Open Source Vendors for Closing Licenses
Where are they?
How can they be heard?
Vote with feet?
Open Source databases are dead?!?
Source Available / Commons Clause
Not Open Source!!!
What are your rights?
Open Source Core
Closed or Source Available addons/features. Do you need them?
Where/Who is the community?
