I like that limited-connection/unlimited time feature. (15 day trials are rarely enough for me, as I might only end up using it once in that time span) A few newsreaders limit trials to a set number of times run, which is also OK -- unless the software needs a lot of re-starts.
Also, the reverse is true, sadly all too often. I think a major factor might be the size of the company -- and the number of lawyers they employ.
When Sony started infecting millions of computers with its infamous Rootkit a few years ago -- dangerous malware by any definition -- many of the major AV companies (most notably Symantec) steadfastly refused to label it as malware, at least until the bad publicity became too much to bear.
