> Sustainability and Monetization: How can open-source projects develop sustainable business models without compromising their core principles?

GitHub has its Sponsors program[0]. You can still contribute code safe in the knowledge that you can bring home the bacon if you've managed to get people to sponsor you.

> Dependency and Corporate Support: Given the heavy reliance of big corporations on OSS

Corporations depend on OSS, but they should compensate the developers if the project is a cornerstone of their service/product. This does happen, and I've seen it happen.

> Licensing Challenges: How effective do you find the current open-source licensing models, especially in terms of commercial use? Are there ways these licenses can be adapted to better protect and benefit OSS developers?

It's important to distinguish between 'Gratis' software (free as in free beer) and free, as in 'free speech'. If it's the latter, as in the FLOSS model, developers getting compensated is often a bonus and not the main goal.

> Community Engagement: What strategies have you found effective in building and maintaining a strong, active community around an OSS project?

Do cool stuff, tell people about it. It's that simple. Social media is one way. Another is through word of mouth. If the project fills a gap in the market, people will notice.

> Comparison with Proprietary Software: In your experience, what are the key advantages and disadvantages of OSS versus proprietary software, particularly regarding innovation, quality, and user engagement?

Proprietary software is often closed source and doesn't have community eyeballs on it, so as opposed to FLOSS, it's inferior, but still often needed (I use Windows for example, because I have to, but default to Linux for everything else).
