Dating apps are toxic as it is, and the fact that most of them are basically days mining operations at this point makes it even worse (this also heavily impacts the overall ux). I have a friend who has worked for multiple dating app companies and it sounds awful.
I think an open source one that respects user privacy would be amazing, but honestly would likely be useless, as barely anyone would use it because people don’t really care about privacy, and select dating apps purely based on user volume.
In addition, and although this is gradually changing, tech and therefore tech-related interests such as data privacy and FOSS are still overwhelmingly dominated by cishet white men, so I can’t imagine such an app having even the most basic, binary requirements in terms of diversity.
I have strictly instructed my family, including my wife, that if I ever develop alzheimers I want to be euthanized. If I am sufficiently lucid at the point of diagnosis I will have no problem overdosing on something and going out in peace.
