Changing the search engine of existing installs is quite questionable and it is worrying that this was released without a much bigger discussion involving not just the maintainers of the browser package going by their personal feelings. If I was a debian user I would be mad.
Debian being free of cost, I dont think you have a right to be mad about anything if you don't help with maintenance. Open source maintainers are not your employees.
Users can always switch back to Google if they so desire.
