Well, I payed to use Ozseek a few months ago, before I found out that it was combined with lazseeker. It made me happier to know that what I paid was going to contribute to keep this site running. I would rather pay $15 (not very much at all really for a whole year of usage... bet you could scab the money out of your parents considering it's for educational purposes... I did lol) for a service than put up with annoying ads that I would just ignore anyway, hence not supporting the site.
Think of all the stuff you get for free on this site... the notes, boards etc. You act as though BOS is stealing from you by removing lazseeker, taking something you own, when it belongs to laz and he can choose to give it away or sell it. If you wrote a novel that was good enough to get published, would you just put it on the web for free, or sell it as a book???
I really don't think this classifies as "selling out" at all. People need to think a little more about what it would take both financially and time wise to run this site... nothing is free!! Web servers cost a lot!!
