If you look at all the studies uncritically and average out their findings, then the safe amount of eggs, imho, per week is between zero and two.
The study of the health outcomes of egg consumption, in general, is a bit out there. A 2009 study claimed the opposite, that 7+ eggs a week increased the odds of cardiovascular disease. There's a strong anti-vegetarian pop-culture under-current right now fueled by the alt-right, keto types, and 'masculinity' experts so small single studies like these will get a lot of attention, but I'd wait for someone to try to replicate it, or at least see it as one data point in hundreds of reputable egg studies that mostly seem to contradict themselves. The egg industry is a $10bn industry and politically very well connected. Some of these studies may be influenced by that. Evolution didn't seem to design us to regularly eat the eggs of other animals and we seem poorly adapted to do so.
Fun/depressing fact: There's one caged egg laying hen for every American.
