eBay stops me from typing in the thing I want to search for so they can try to persuade me to use the app that I have expressed zero interest in for a decade or so. Guys, I'm trying to press money into your thieving little hands - why are you trying to stop me?
Reminds me of Austin Powers:
21! Blackjack,
"Hit me!"
"...but Austin!"
"I also like to live, dangerously."
They see it as a win because you've still been using their site for a decade now, and every time they advertise their app there's still a non-zero chance you'll relent, but if they stop pushing their app, that chance drops to zero.
The only winning move is not to play.
