The Reddit search for Lemmy also gives these privacy copy-pasta as top results when searching for Lemmy. I'm still betting that Reddit employees are involved in boosting these posts.
That's actually hilarious. Once you analyse it, it boils down to three things:
Ad hominem towards the devs. It's so idiotic that I won't waste my time with it.
Conflation of the flagship instance (lemmy.ml) with the platform as a whole. As if you had to use lemmy.ml to use the platform (you don't).
Incorrectly assigning privacy concerns of social media as a whole to Lemmy in specific.
The third point actually deserves some clarification: no matter if it's Twitter, Reddit, Facebook, Mastodon, Lemmy or any other sort of social media, you should be extra careful with what you share, as it might eventually bite you back. It is public communication, treat it as such; it is not private conversation. Regardless of Lemmy storing it or not, consider what you share publicly with the internet as potentially staying forever, and be mindful with it.
So all three points are actually invalid. This might convince some irrationals to stay clear off the platform, but frankly? This is actually good for people here.
Yup - and there's always the issue with third parties storing this info. Reddit has been archived, for example; so no matter what Reddit Inc. does with your data, it's still "on the internet".
I suspect they do, in fact, understand the difference. And are intentionally conflating lemmy the platform with lemmy.ml the instance in order to dissuade people from using the platform, since they know that most people new to the platform wouldn't understand the distinction.
