You do not have to install Gator if you do not want to. If you don't like it, don't install it. However, this option is there because the LW team members need to eat and have a roof over their heads too. This software generates a little revenue for them so that they can continue their operations. Did you know that bandwidth costs alone are costing them over $10,000 a month?!
Please try to understand their position...
