Why does anyone care? Just ignore the poll and download whichever browser you want to use. If it was actually stopping me from downloading the other browser, then that's a problem.
This is the same as an advert popping up. Just bat it away and carry on as normal.
The issue is that adverts built into the OS, and into browsers shipped with it, are regarded incredibly poorly. Regardless of the ease of bypassing them and how little impact they have, they simply should not be there in the first place.
