In the traditional media, many (not all) news agencies with any kind of credibility at all generally have rules against freebies in most cases - and disclosures about them when they do accept freebies for a reason.
There are issues of objectivity.
The issues are even bigger when, instead of a newspaper that covers everything, it's a Web site that covers a single company - and is accepting freebies from that company as part of that coverage. In fact, in many ways relies on freebies - whether it's a gift or just special access - for that coverage.
There comes a point when you need to know if this is an objective source of good information or essentially a secret extension of the company's marketing.
In any case, I can't speak to anyone else here, but I know I would love it if Ricky would enter the conversation here and explain his views on these things/take questions regarding it.
