Sea level rise is measured in millimeters per year. When a platform is already 20-30 meters above the sea, the handful of centimeters of sea level rise over its lifespan is completely insignificant.
In fact, this state of affairs has not even changed that significantly.
Real structural changes are hard to enforce. There is always something more pressing, just look e.g. at the 100 billion Germany spends on war (how many trees that would give?). As a politician it would be the end of the career if you tried to enforce something really drastic (and so nobody does it, incl. "the greens").
Ok I'll blame them for that then.
The investigative research that brought this up was a big development in proving that they knew on an institutional level that the science was real.
The direct quote from the complaint (found here on page 5: https://cdn.arstechnica.net/wp-content/uploads/2018/07/show_...) would be: Meanwhile, beginning in the mid-1980s, Exxon and other major oil and gas companies, including Mobil and Shell, took actions to protect their own business assets from the impacts of climate change, including raising the decks of offshore platforms, protecting pipelines from coastal erosion, and designing helipads, pipelines, and roads in the warming Arctic)

Glad to know people will still be pedantically splitting hairs as the world literally burns.
edit: at least someone who sells bullets or guns has the excuse that they can be used for sports or entertainment. If you pull oil out of the ground, it's meant to be burned, made into plastic, or put outside to roast in the sun.
The people murdered with guns are murdered by people, not by the manufacturers of the guns.
Doesn't mean that gun manufacturers are nice people, but at least we wouldn't be making ridiculous statements and we could communicate what we actually mean accurately so that we can have a productive discussion.
