It is not about that. Sync for Lemmy is five times as expensive in comparison to the Reddit version, plus it is a subscription model. Pure evil. I am not even adding that the whole platform is FOSS, but Sync. Pay money to Lemmy if you want, not to a greedy developer of a client. Lemmy has no ads, only donations. Yet, people are buying the "good UI" BS. Develop Lemmy per se, not a proprietary parasite. Or pay to server hosts. No, people pay to someone who has nothing to do with the Lemmy itself.
Sync is literally made off the spyware: https://reddthat.com/comment/1586624
UPD. Couldn't care any less about someone else's feelings. I am pro-facts, these won't take into account how you feel. Actually, no one cares about those
Keeping the Reddit sub makes sense for one reason. There are tons of thread, and answers. When you search something, Reddit comes among the first options. Fedi hosts have different links, hence it's harder to find.
