I think I understand what you mean, but to me the exemption doesn't seem performative. It seems like the equivalent of him talking to his employer and having them agree to not force him to use tech he is concerned about, he just used a particular legal avenue to justify it as part of that discussion. It may be performative in the sense that it also got attention (e.g., in the form of this article), but in this case even that part of it seems like it could be a useful precedent for others who may be considering a similar route.

Then again, maybe even seeing it as _slightly_ performative, potentially, is overly pessimistic. It may seem performative simply because it's novel, but if he legitimately considers this part of his religious beliefs and his employer (seemingly) agrees, what is performative about exercising his rights like many other people of other religions do?
