Just go to Open Office or Ubuntu's website. They have torrent links to download the softwares.
There are some sites exclusively for legally free torrents.
Utorrent.com doesn't host torrents, its just a software's homepage, which is still no reason for hacking them.Don't get me wrong, i am not supporting the hackers, but there is a nice saying "as you sow so shall you reap" is proved here.
I didn't say you are supporting them.And yes i would certainly not feel good if my system is infected with a malware, but honestly i cannot complain also.
Another thing applauding ones' achievement doesn't mean i am laughing over others defeat. I fully sympathize with the infected users but that won't stop me giving +1 to the hacker(for this time atleast).
I fail to understand what the hacker's "achieved". What did they gain by this? Their act was sadistic and cowardly.
