> Instagram didn’t do it, Twitter didn’t do it, Facebook didn’t do it. None of the mobile apps in their space did what TikTok was doing. Why was TikTok?

Who knows. You don’t, at least.

> You made arguments, none of them are a good reason for copying clipboard data every second and then suddenly changing that behavior with no functionality loss.

Plenty of apps did it, and the functionality lost isn’t always clear to the user, or, like I already said, it was just written a different way so no function was lost.

> Did they ever give a good reason to be doing it? They haven’t.

Sure they did. For instance:

> Following the beta release of iOS14 on June 22, users saw notifications while using a number of popular apps. For TikTok, this was triggered by a feature designed to identify repetitive, spammy behavior. We have already submitted an updated version of the app to the App Store removing the anti-spam feature to eliminate any potential confusion.

Other apps did similar. Also, it wasn’t “every second”.

> It would seem from a PR perspective if it was for some user functionality benefit you would just say, our bad, we did it so we could parse youtube links automatically for you. They didn’t do that.

They did do that.
