Because almost all manufacturers outsource the footprint creation stuff.
And one sometimes finds mistakes.
What are the usual places for you?
I rarely find proper footprint+symbol on snapeda for example, plenty of plain wrong or subtly wrong are however found on regular basis.
I hope you are doing well! This is Ron Publico from SnapEDA and we want to help you regarding your experience about our footprints and symbol at SnapEDA. May we ask if you can share us more information and send us an email to support@snapeda.com?
Our team is more than happy to help you and investigate those footprint and symbols that you have check earlier.
I'm sorry, but SnapEDA is one of the companies specifically making the library situation worse (Altium comes in first place on that front, though).
For a while, everybody was shipping Altium libraries. This was really good because, as we well know, engineers are lazy. Thus, somebody would simply pack up their internal libraries and ship them. This meant that every symbol had been shipped and tested in a real product. Consequently, the libraries generally didn't have any fatal faults. And you could extract the symbols and make whatever edit you needed to fit into your own library management stuff.
And then Altium decided to enshittify things in order to extract rent from library management. Now, you couldn't extract symbols or footprints from a library, or you had to register with their cloud garbage.
And then SnapEDA and its ilk came along to "fix" this problem that Altium just caused. Except that engineers are lazy. Nobody uses SnapEDA for actual internal libraries for production boards inside the semiconductor companies. Consequently, the libraries have minimal feedback and you have to beg people to send you fixes. Which, of course, they don't do because engineers are lazy.
And don't get me started about the "licensing terms" behind using SnapEDA symbols.

I was still able to extract sources from integrated libraries in Altium 22 and I have no cloud integration turned on.
Was there some easier process in the past?
