Well then logic dictates that whoever wants a 50/50 split should at the very least show more positively to the business with less share in order to do their bit to balance share.
Yes?
No it doesn't. Your statement above implies that one must voice support based on market share, rather than technological merit. One can want competition without thinking that makes it okay to praise something not worth praising. In the hierarchy of bad behaviour, dishonesty ranks as worse than standing by and not being a warrior in the war of corporation market share, imo.
Plus some people are just critical generally - that doesn't mean they're biased. One doesn't need to show "positivity" to not be biased. You can be enthusiastic, you can be negative. Neither are biased inherently, only when you favour one company more than the other with the positivity / negativity.
So for example, D.P. will be endlessly negative about AMD. Call
them out for bias and you'd be correct. You are endlessly positive about AMD. Again, there's an obvious bias that
you could be called out for. Positivity is not more or less biased than the negativity, it's just a different approach.
I myself have a bias towards AMD, but it's purely on the purchasing side. I will prefer to buy from them where they meet my needs because I want the company to come back from where it was and establish itself as a strong force in the market. I both believe this would be a good thing for all of us and I have also been very impressed with what the company seems to have been doing. It's a company that is something like 70% engineers. I
want to support it. But I wont extend my bias into partisanship online. At least I hope not. I do tend to say more positive things about AMD but that's mainly because I have been following the news on their products more closely and know more about it.
TL;DR: I don't think you should be attacking Seanspeed for bias. In fact, it's generally bad form to do so unless you have some special evidence. Like D.P.'s debacle over TDP from general familiarity with their posting, I'm happy enough to stand by an accusation of bias there and I'm pretty sure most of the rest of the forum knows it too. But generally such accusations don't do much other than incite the flames. They should be avoided. Bring facts and fight only with facts. Not being super-positive about something doesn't prove some terrible bias. It may just be that they don't buy into the whole Us and Them mentality.
Which is a good thing.
