The only realistic thing that the NDA could have contained was stipulations around leaking details about Threads. Who cares. Some admins probably wanted an inside look so they agreed to not leak any details. That does nothing to put their instances under the control of Meta. Yeah sure the admins are “controlled by the contract”… to not share any secrets about Threads. Again who cares.
People dreaming up scenarios about the NDAs including clauses that let Meta control instances or their admins are delusional. As someone working in tech I sign NDAs all the time when I visit my friend’s companies. It doesn’t mean they have any control over me besides stopping me from leaking stuff that I see inside the company.
My understanding of the term (from an asian american perspective I guess) is that it at most has a connection to race through the origins of ricing, and since the origins and current usage has never seemed derogatory and is simply about the Asian origins of automotive ricing I don’t think it’s racist at all. I see it as no different to any other term that reflects the origins of something that is connected to a specific ethnicity, especially when the term isn’t derogatory and isn’t used to otherize (which is how I consider model-minority stereotypes to be racist despite not being “negative”).
