Slowness for some users: https://lemmy.dbzer0.com/post/36299751
Lack of updates on LW. At this moment, LW users still can't delete media they uploaded. That was a big deal in March 2024: https://tech.michaelaltfield.net/2024/03/04/lemmy-fediverse-gdpr/. Since then, Lemmy allows it since 0.19.4, but LW still runs 0.19.3 (there are plans to update, but at the moment we're speaking, it's still not the case)
Power tripping of some LW mods. You can have a look at !yepowertrippinbastards@lemmy.dbzer0.com , with one example: https://lemm.ee/post/49988344/17418849?sort=New
Smaller instances can have issues to keep up with LW due to its size: https://lemm.ee/post/28755787 . Again, those issues were fixed in 0.19.6, but LW is still on 0.19.3.
LW tend to take some debatable policies (https://lemm.ee/post/30444527), the last one being about allowing flat-earthers in the debates: https://lemm.ee/post/52282379. Due to their size, this impacts basically the whole platform.

that post on lemm.ee in your first point is dead

Yes, because the !asklemmy@lemmy.world mod removed it as a "support question".

Pasting the content here:

Most recent example:

the site (or at least lemmy.world) is sooo slooow. Basic functions like loading images take me back to the dial-up era of “click the image then do something else while it loads,” which is downright ridiculous in the 2020s. Again I’ve stuck with it because I want to support the fediverse, but 99% of users won’t.

Additional example

It also doesn’t help that it’s slow as fuck on desktop compared to the others I tried.

Is lemm.ee much faster than lemmy.world for you?

Yes, MUCH. Sh.itjust.works is much faster as well. I don’t know if it’s because LW is still on 0.19.3 or what, but it’s a very significant difference.
