The handwriting is on the wall in bright colors: the halcyon days of point & shoots AND DSLRs for casual, social users are OVER - at least as far as Flickr is concerned.

Precipitous declines in Canon and Nikon use were at the hands of Apple and Samsung -- but especially Apple, as Samsung went flat in 2015. Sony was flat, but this reflects both Sony's acknowledgement that global unit volume of cameras will continue to drop -- and their strategic response of moving up-market with higher value cameras like the RX100 IV [B&H|Amazon] , a7s II [B&H|Amazon], a7r II [B&H|Amazon], and RX1R II [B&H|Amazon].

Camera phones alone exceed the share of DSLRs as "mirrorless" share grew as well -- but remember, camera phones are mirrorless too -- as are most point and shoots.
