Heather Morrison, on the for-profit OA publishing group Frontiersmid-crisis price hikes:

A third of the journals published by Frontiers in 2019 and 2020 (20 / 61 journals) have increased in price by 18% or more (up to 55%). This is quite a contrast with the .4% Swiss inflation rate for 2019 according to Worlddata.info ; 18% is 45 times the inflation rate. This is an even more marked contrast with the current and anticipated economic impact of COVID; according to Le News, “A team of economic experts working for the Swiss government forecasts a 6.7% fall in GDP”. (Frontiers’ headquarters is in Switzerland).

Frontiers is controlled by SpringerNature’s parent company.
