In this session we are aiming at moving forward on the preparation of OW2 members and open source actors in general. More info.

More money for open source software is a never ending issue. In a tech ecosystem built on start-ups, venture capital and data-gathering apps, the fight for sustainable funding for ethical technology projects is a fierce one. After some big victories for open source funding in the last years, this talk is about why we should not forget the small projects coming from and catering to the needs of civil society.

Murena's /e/OS is a new open-source smartphone operating system that offers default features that allow its users to escape the constant collection of their personal data: complete deGoogling, removal of application trackers, IP address masking, etc. It also offers complementary cloud services to the OS (drive, email, calendar, office document management, etc.), all of which are entirely based on open-source software.
Created in Europe, and compatible with mainstream mobile applications, /e/OS is the first customer-centric mobile OS designed with European values in mind.

We will tell you about the trials and tribulations of our company (BIRU, makers of Tenzu) a year after we decided to take on the open-source editor challenge as a cooperative company.
What funding sources were available to us? How much effort was it? What is our business model anyway? What difficulties did we face by being neither a startup with shares to sell nor a cooperative company with a fairly standard business plan?

It is often claimed that open source creators seldom profit from their work, but this oversimplifies a complex ecosystem. Different camps—closed source enterprises, open source companies, public institutions, freelancers, and hobbyists—have varied motivations and expectations regarding their OSS activities. While some rely on open source for income, others do it out of personal or professionnal interest. This raises crucial questions about the legitimacy of compensation for freelance and hobbyist contributions and how to evaluate and support their value in the open source landscape.

The commercial Open Source ecosystem looks stuck between traditional open-core business models, services models and new and awkward business-source licensing which don't even contain traces of open source.
Penpot, the Open Source Design & Prototyping tool, is spearheading a new business model called the Open Nitrate Model and we will explain why we believe it greatly simplifies both product building and business development for an Open Source product at a time where we need to start transitioning into a new social contract around Open Source licensing.

Automated inventory is a fundamental pillar of ITSM service management, but why? And how can it be integrated into a broader asset management strategy?

But how does this impact its economy?
What does that mean culturally?
What about hardware, data and AI?
This talk will discuss the global, European and UK landscapes in openness in software and AI and delve deep into the data whilst taking a holistic approach to policy and strategy.

Understanding what is inside an application is critical for effective vulnerability management and risk assessment. By identifying the components within the application, you can identify and address potential vulnerabilities more effectively and assess the overall security posture of the application. But if the source code is not available or identifiable, then that is more of a challenge.
