I'm in agreement with her. While I'd like things would be different, I don't see how people can think that the fediverse / #threadiverse as it stands now is a suitable replacement for Reddit. The entire labour strike on Reddit is centered around inadequate community moderation tooling and their API-reliant alternatives threatening to become unavailable.
Lemmy is fediverse's main answer to Reddit. Moderation tooling in lemmy is severely lacking and admins put themselves and the communities they host at risk by using that software in federated mode. I wrote this github issue over a year ago: https://github.com/LemmyNet/lemmy/issues/2277 very little has changed since.
In it, I give the example of a user account where description avatar are all slurs and hatesymbols. The account is replicated across all Lemmy instances that existed at the time that account was made, and admins can do nothing about it. For fun: try to change the domain name of the account to any lemmy instance that was around at the time.
The way the main devs are handling that issue also does not inspire tremendous confidence. I'd say in a trusted group lemmy is mature enough to use, but definitely don't turn federation on..
