Cheating is when teams are running illegal cars for example, strong rumors existed around the Schumacher championships with Benetton that they were illegally using Traction Control to boost performance.

More recently Ferrari finding a way to circumvent the FIA provided fuel flow sensor allowing them to push more fuel into the engine than allowed.

That's cheating, and no huge problems like that existed last year. Sure there were the usual things. Aerodynamic parts flexing, not proved to be illegal as it passed all FIA mandated tests. It leads to a new Technical Directive in which the FIA reminds teams that aerodynamic parts shouldn't flex and that the FIA is improving the tests. No punishments, no points deduction and no rumors or whatever existed.

The final race isn't cheating, if a referee makes a mistake in a football match you can't accuse one of the teams of cheating. Even Mercedes commented within hours after the race that Red Bull and Max Verstappen did nothing wrong; they did what every team and driver would do. Win the race given the chance they had.
