You're right, but this is the sort of thing that gets blown up by the media and used to shut down privacy-friendly platforms.

Maybe it's a slippery slope fallacy on my part, but it's not unimaginable to consider the idea that legislators could try to take down an enitre platform based on something like this. Just look at some of the proposed privacy-antagonistic legislation that's been introduced recently to see what I mean.

Many Lemmy users wish their niche communities would become more populated. For goals like that, the reputation of the platform is important. I also don't want to get into defensive debates when revealing to someone that I use Lemmy.
