Lot of very good programs are Open Source and gone so far that any backshit would not even survive 2 days!
Must i quote them? Gimp, MPC - HC, FileZilla, FFDshow, Mumble, Open Office... etc..
Piriform is very famous with CCleaner, and going open source is a good way to be even more known!
Recuva is great, but recuva is not complete.
Going open source would increase the amount of work done every day for it, and would speed up his growing.
Going open source would increase the amount of donations for it, as people who like freewares, LOVE opensource AND free softwares.
I prefer donate for "la cause" than for a private group that may switch to selling products (a lot already done this)!
If you are always looking darkness, you'll never see the light behind.
