This is how donations work.

Moderators volunteer to help the forums right? Fine. That saves Comodo time & $$. You guys help mods, That saves Mod time, and then everyone is happy and Comodo is still giving away free products ! haha...
I know... pretty short and random but the point is, Comodo care more about end users and protecting YOU on the internet, with free software AND making $$ in a different way (SSL Certificates), then asking for your hard earned cash ! So that way, it's a win-win situation !! That's the way I see it.
