Kevin Systrom and Mike Krieger quit Facebook, six years after their company Instagram was acquired by the largest social network.
The departure of the founders of Instagram came at a time when their idea is gifted as charismatic and over a year with a lot bad reviews for Facebook.
So with all the challenges faced by Facebook's basic application, it will be important to continue to protect Instagram's vision and not allow it to be downgraded. Facebook has long faced the mistrust of its users (and not only), governments, security specialists, and personal data protection activists. 
The reason for the departure of Systrom and Krieger was their dissatisfaction with Zuckerberg after trying for a long time to exercise greater control over Instagram. It is not clear, however, just what was the point that exasperated Systrom and Krieger.
Wall Street does not seem excited about the news, as Facebook shares fell in the morning after announcing the departure of Instagram founders.
Είναι πολύ νωρίς για να πούμε τι θα φέρει αυτή η αλλαγή ηγεσίας στο Ιnstagram, μια service που έφτασε πρόσφατα στο 1 δισεκατομμύριο μηνιαίους ενεργούς χρήστες. Ωστόσο, παρακάτω θα τολμήσουμε να αναφέρουμε τρεις αλλαγές που μπορεί να δούμε πολύ σύντομα, υπό την ηγεσία του Facebook.
More alerts between the two services that will encourage the intersection of Facebook and Instagram data
One of the sources of tension between Facebook CEO Mark Zuckerberg and the founders of Instagram was Zuckerberg's desire to display more cross-publications between Facebook and Instagram.
TechCrunch Reported Facebook was in the process of adding a shortcut to the Instagram bookmark menu, while Bloomberg he says that some Instagram users were starting to receive alerts when their friends posted photos in their Facebook main application.
Following the resignation of Systrom and Krieger, they are being replaced by a high-profile Facebook executive. This will open the path for the cross-exchange of information between the two services.
There are many reasons why Facebook wants to do this. The number of active users in North America – where the average revenue per user is higher than in the rest of the world – remained stable on Facebook's main app, while it was much higher on Instagram. Furthermore, the base of Instagram users is younger than Facebook's base, so getting these Instagram users from Facebook is critical to building a customer base across two different apps.
More ads in Instagram
Zuckerberg said he believes more users will share content in Instagram Stories instead of the traditional news feed in the coming years. Instagram Stories has so far been very promising, as it has more everyday active users from Facebook's Stories.
Most ads come from Facebook and not from Instagram, but Instagram has more end-user involvement. Facebook will not miss the opportunity to take advantage of more advertisers from Instagram. We should expect more aggression on ads from Systrom and Krieger.
Experiments with Instagram algorithms
The new head of Instagram could be Adam Mosseri, who was responsible for Facebook's News Feed. Mosseri was previously one of the people responsible for redesigning Facebook's Big News. This year he gave priority in presenting content from family and friends instead of content from pages and such.
Instagram's News Feed faces different challenges than Facebook. Fake news is still a problem, but less intense than Facebook, as the platform has fewer users. But on Instagram, there is more bullying, which is particularly worrying given the younger members of Instagram. Last year the company added a filter that users could add to hide aggressive comments. This year a filter was added that aims to hide comments that "offend a person's well-being or health".
At a time when Facebook is facing similar problems with toxic discourse, Instagram could be an important testing ground to determine what it takes to develop and maintain a healthier News Feed.
