I'll grant you that language is potentially a dogwhistle, but on their blog, they post about Earth day and Sustainability, which is currently vilified by MAGA.

If I had to guess, their marketing team is trying to play both sides.

Without more clear evidence of their politics, I'll probably continue to recommend them if they get people to stick with saving water, as ultimately that's the opposite of what Trump's policies are trying to do.

Since the flow regulators became standard issue in the 90s, showers are not as good as they were. While the specific messaging may or may not have another meaning related to us politics, it seems like they stand for better showers while using less water, and that seems like a good mission to me.
