There is nothing wrong with LinkedIn or other social media posts. Quite the opposite. They provide good background information both on a general level and more specific, important info.
For example, that Gitex Africa event post you shared contained significant information for shareholders. We learned about the BP (Big Pharma) partner and also the algorithm that will be utilized.
That algorithm for chronic kidney disease was also yet another confirmation that fundus images can be used to screen for much more than just retinopathy. In fact, a screening for dementia/Alzheimer’s was already introduced in China, which is the result of international cooperation and not just a Chinese thing. That also uses fundus images. So, over time, a good bundle of different algorithms for various diseases will be added to the Lumo camera.
AstraZeneca, which was revealed at the Gitex Africa event, is not necessarily the only BP company with which a partnership agreement will be made. Roche, which has been featured, and others are also entirely possible.
AstraZeneca is an excellent reference for Optomed and the Lumo camera. One could certainly consider that joint presentation at the Gitex event as a semi-official partnership announcement.
