Having been involved with IOSA audits in the Middle East, it's not really that great a deal to become an IOSA registered airline. Why are you making it out like OA doesn't have what it take to survive such an audit?
Whoever's been telling you otherwise once again have an agenda and vested interest to see the demise of OA.
This airline has already proven time after time that it has done what's needed to be done and more to progress, improve and evolve, and will continue to do so. They're good at dealing with shifting goal posts....damn good.
