Unfortunately, I don't think we're going to ever be getting an ethical dating app. It may be ethical as far as not charging users to connect, or not trying to keep users constantly staying single so they are always using and checking the app. Without that "addiction" potential, I think even a completely open dating app would fail miserably. If people were able to connect and move on quickly, there would be little reason for the app-creators to continue developing.
I say this as someone that has spent the last few years wading through various dating apps, looking for a monogamous relationship. The best luck I've had with dating (after using Tinder, Hinge, Bumble, and Facebook Dating) has been finding local Facebook singles groups, and just chatting. I can be nervous and awkward, but I'm able to fake it in person, and online it's easy for me to have conversations with others about interests.
Also, instead of trying to be a "normie" (although you didn't say you were doing this, so this may not apply), lean into what makes you unique and try to find the same or something compatible in someone else. Going through apps is not fun, but I have met a ton of different people that I don't think I ever would have interacted with if I hadn't gone through dating apps or chatting with strangers.
To be clear, the language isn't "fun" for anyone that has dealt with any of the things they mention!
