What do you think about future of Open-Source in tech industries?

I think that startups and existing companies need to focus more on their own dedicated open-source programs. Open-source is very underrated when it comes to startups. The following ways I believe open-source can help startups are: 1. Hiring process 2. Community building 3. project Management 4. Marketing 5. Building subsidiary products 6. Testing MVPs 7. Implementing side ideas 8. Get to know about the latest techs in the industry 9. Involving youth 10. Help students to grow with your startup what do you think about it PH community?
