Steve Johnson has accused the ATP of protecting themselves rather than looking out for the interests of the players.
The coronavirus crisis has necessitated that most tournaments are played without fans, which has seen prize money take a major hit due to no ticket sale income.
Johnson, though, says while he can understand the reduced income, he can't accept players being the ones to carry the burden of it.
“We players are always told ATP is such a great system cause we are “equal partners"," Johnson wrote on Twitter.
"Well, what type of system allows Masters 1000 events to pay 60% less when BNP Paribas Open is trying to host their event at 100% but can’t get approval because other tournament directors are ATP Board members and they want to benefit from these reductions?
"The conflicts and lack of transparency are what hurts, not just the players but the sport.
"Everyone loves to throw around “it is about what is best for the sport,” but the actions don’t match the words.
"These latest two examples reveal that, all too clearly."
Johnson also commented on the Roland Garros postponement, joining the likes of Daniil Medvedev and Milos Raonic in criticism of organisers.
“Roland Garros once again unilaterally decides to change the date of their event, disrupting the calendar to accommodate themselves without respect for the consequences and impact it has on the rest of tennis."
