The worst offender I've seen in this regard was some GUI program on Windows, and it had this checkbox in its installation process with some wording like this:

"Please do not uncheck if you do not wish to not install XXX (bundled bloatware)"

I just assumed that the default state must be installing the bloatware, and changed it, and fortunately I was right.

"I just assumed that the default state must be installing the bloatware, and changed it, and fortunately I was right."

That's how it is usually and also my way to navigate modern UI.

"No, I don't want to share all of what I do on my device with you and your 800 partners"
