Hi Guys , I have a query

I watched a lot of ondas drones videos. It's a great company. I saw FAA certification. Only Ondas has it , then why other companies are struggling to get it . Over these years ondas has been focusing on research and acquisitions instead of revenue. Are they waiting for these certifications so that they can fully concentrate on the revenue side ? Just a query. I am a beginner investor. Happy to receive criticism and feedback.
