"I don't understand why I was penalised", the Racing Point driver said. "We have nothing to do with the money shift [between the teams] and all that stuff".
He added: "It's really important that people realise it's not the drivers fault ─ this is a constant cycle of F1 for years and years".
"They've got to make some serious changes to the decision they have already made for how 2021 should be". It's still the same.
"It's still the same and until that [rulemaking] structure changes it will continue to be the same in my opinion". That's not my job to do that. "How it's set up, just from watching when I was there, it's not good - really not good", he said.

Hamilton arrived late to Le Castellet, attending fashion shows in Paris and a memorial for designer Karl Lagerfeld on Thursday.
"But I am encouraged that Ross (Brawn, F1 director) and his team are working, for the first time, on a real aero package that hopefully will have an impact". I think there was the FIA and all the Formula 1 teams.
"I have nothing to gain by being there but if there's anything I can help. they've been making all these decisions and never once had a driver's input in that room, so if that can be the decisive point that helps shift it and the fans can get better racing, I will be proud to be a part of that".
Hamilton was accompanied at the meeting by Grand Prix Drivers' Association chairman Alexander Wurz and Renault driver Nico Hulkenberg.
Mercedes team boss Toto Wolff recognized fans would have a different view to those who lived the race from the pit wall with access to all the team radio conversations.
