I find it distasteful to see <BIG COMPANY> using such a big hammer against a little guy who just posted a link. "Real" IS an English word, after all - their protections are therefore more limited. "Real Alternative" seems rather descriptive, and not at all confusing to consumers (as well as having a clever double meaning).
On a related note, I consider the early Real Player software to be malware, due to it's Trojan installation of other software and aggressive attempts to prevent removal. I've lost all trust in Real Networks - one of the reasons they've spun off their music service as a separate entity, I imagine.
The market certainly punished them for this. But were they ever taken to court over these practices (and violation of Computer Fraud and Abuse Act)?
