We can’t force people to join, but we can emphasize the negatives of Reddit and the ways Lemmy solves those. Things like:
- Lemmy does not collect personal data and share it with third parties like Reddit does
- Lemmy does not violate your privacy with tracking or ads like Reddit does
- Lemmy’s code and algorithms can be viewed and reviewed by anyone at any time as-is, unlike Reddit
- Lemmy is 100% self-funded and moderated by its own users across the world. Reddit and your data is governed by a single money-driven corporation with controversial leadership
People that value those things are the ones that will consider moving over. You might say that you’ve read over Reddit’s terms and conditions, and then present the Lemmy community as a private and safe alternative if anyone wishes to join?
