It's not the first time it happened, the entire editorial board of Topology[0] resigned and went on to create the Journal of Topology back in 2006~2007, and over way less than the Lingua demands: Topology's editor just wanted better (lower) pricing policies. Same story for the Journal of Logic Programming (in 2000), the Journal of Algorithms (in 2003) or the International Journal of Solids and Structures (in 2005).
