Yes, the new government diminished subsidies and price controls. Bus rides in Buenos Aires (which are heavily subisidized) went from ARS 25 (USD 0.02, ) to ARS 260 (USD 0,25) and gas went up from USD 0,25/litre to USD 0,80/litre. So everything is still dirt cheap af but not as much as before. Compare that to São Paulo's R$4.4 (usd 0,9) bus rides and R$5.75/L (usd 1.15) gas prices.
