That is a fair point, regulation often gets watered down as it undergoes revision after revision, though in fairness, most cases can not be solely blamed on US tech.
The stricter timetable for an ICE ban, to use something mentioned, was mainly changed due to pressure from European business interests, including in part Poland, Germany, Austria, etc. Essentially countries with a significant Auto industry that hasn't pivoted to EVs in the same way as e.g. France. I did not hear of Exxon lobbying to that extent in this case, but maybe I just missed that.
Basically, whilst US concerns definitely have their lobbying efforts in Brussels and Strasbourg, we need to be aware that European business is just as able and willing to engage in the same. The lack of interest in European politics compared to the national level tends to make this more frictionless and effective too, though that is a bit of a chicken/egg problem. People won't engage much with EU politics if the EU is seen as overly bureaucratic and lead by lobbyists, but there is little incentive to change without public interest.
Still feel that regulators can do tremendous good if motivated. The US has shown their abilities during Dieselgate, the EU in data protection. We, the public, need to tune in. Writing letters and calling does make a difference, as hard as that can be to believe.
