I can think of one such company. Full disclosure: I work for them. It's a successful startup where the entire retention strategy is for our product to be so freaking amazing you'll never want to use anything else. It's been working very well so far. But our product really is freaking amazing.

Since I posted I thought of another one (assuming you don't work for them). But, they really are rare. I see dark patterns everywhere, so I have a visceral reaction to any claims that companies respect users.
