I don't think anyone here advocates for "just ship it" when you're talking about breaking updates to a system used by a significant chunk of the world's population.
I don't see how you would get the private key for the airtag off the iPhone without jailbreaking it. The readme of the project implies you can do this but the docs are completely lacking
The "model solution" isn't exactly great. "Just make sure to style the button so it's appearance changes when it has focus..." Ok? So show me how to do that!
My computer isn't great, I'll admit, but I'm making a relative comparison. I visit many different websites on my low spec computer but discord is a noticeable outlier on how it affects the performance.
