Not sure how serious you're being here, but..
1L rule applies to everyone, so idk what you're complaining about. It's been in the rulebook for ages and the teams are well aware of it. The embarrasing part is that no one at Aston Martin noticed it until it was too late.
As I already discussed after the previous race, the stewards can't take the championship or race positions into account when judging penalties. It would skew every incident between rival teams and lead to everyone looking for something that isn't there, like the Bottas incident. Is it fair? Probably not. Does the same rules apply to everyone? No, there's clearly been instances where the stewards have looked the other way to favour one of the top teams (Leclerc in Monza 2019 for example), in the same way how NHL refs swallow their whistles.
Also surely you aren't suggesting that Mercedes did the two crashes on purpose? Bottas is arguably the worst wet weather driver of the modern era, so it shouldn't come as a surprise that he f***ed up.
