Add to that list:

- showing focus-stealing modals when loading the page/app, which breaks the quick look functionality on iOS

- interrupting your workflow with tutorial popups (especially multi-step ones that point to different parts the screen) that demo or upsell a new feature, requiring you to dismiss them to continue

- not having an option saying "I'm a power user, stop explaining shit I already know"

To be honest, if the concept of growth hacking was erased from the universe, pretty much none of this crap would exist. Atlassian, Browserstack: I'm looking at you.
