Yeah but the same argument could be made for the web. Why build a react app that complicates everything instead of just a plain HTML site. The simple answer is use cases, if you're delivering a simple email with a notification then no you do not need something like this, but some will have a case where they do need to reach for something like this. It's no different than web or mobile development. If we shunned every piece of tech that had potentially nefarious uses cases then we would still be stuck in the stone age.

Humans prefer to have barriers to completing a task removed. No clicks is much better than one click and privacy is almost completely dead. Privacy will slowly die unless there are major changes legally and culturally. It’s worthy to fight against the loss of privacy. I think it will be a losing fight though.
