I disagree slightly. It may not be good business, but it could be good PR, situationally. I expect a lot of 2nd-tier distros will refuse to implement it, and see a boost in their installs as a result.

Debian, Ubuntu, etc., they'll all fall right in line because the clear and immediate losses will outweigh any PR issue.

When they fall in line and add the age bracket drop-down menu, we'll keep using them because throwing a hissy fit over a distribution allowing you to select your age bracket is very obviously stupid.
