Adam Mosseri, Instagram boss, spoke about the controversy growing on its platform:

We definitely have a number of photographers who have been upset. I want to be clear: though we are leaning into video, we still value photos. Photos will always be a part of Instagram. Source: Instagram showed people too many videos last year, admits Adam Mosseri - The Verge

If you like photography, go elsewhere than Instagram. They focus on user engagement, not photography. There are so many great platforms these days that are built for photography enthusiasts.
