Sony - When the ps3 came out it had the OtherOS feature that allowed users to install Linux. This was the main reason I bought a PS3 instead of other systems. From the beginning, it turned out that Sony crippled the OtherOS by restricting resources that were available to it.

After a few years, they removed the OtherOS feature, because someone hacked it, which could possibly lead to pirating ps3 games.

They sold me a PS3 based on a specific feature and then disabled that feature. I will never knowingly buy a Sony product again.

Same here. I had a bunch of their CDs and downloaded a few Metallica songs. Then I got kicked off of Napster after they sued, and haven’t been able to listen to Metallica since then. I’m not boycotting them, and they’re within their right to sue, but the whole incident just soured their songs in my mind.
