This is really the terminal issue with Reddit alternatives. They are just Reddit minus the most recent controversy as of foundation. Reddit is overall just a popular content aggregation website with poorly design discussion features.
Upvotes and down votes, while intended to help users weed out bad arguments and spam, only achive in promoting sophistry and tribalism. What ends up getting upvoted is what “wins” the argument, while good arguments that come from unpopular viewpoints get downvoted.
And with that comes all the toxic elements from old Reddit ruat we all hope just won’t be a part of our replacements. Reddit’s format works at a smaller scale, where users are typically more enthusiastic and therefor better informed, but as the sites get larger you’ll notice they typical hyper-snarky “owned with facts and logic” attitude take hold of a community as more people with a weaker investment jump on the bandwagon and upvote everything that makes them feel smart.
Eventually, the site becomes just like Reddit, but for a smaller and more insulated community, and users begin to question why they’re here instead of Reddit which has the established user base that can reliably cover more topics you are interested in.
We have not learnt from history, and we are doomed to repeat it. Maybe it’ll be different in the future.
Being open source doesn’t stop the inherent flaws of the Karma system or the increasing toxicity that correlates with platform population.
It’s really cool that Lemmy is FOSS, don’t get me wrong, but that’s kinda irrelevant to the issues presented.
