I'm not tracking the people you see as offenders, meaning I don't know who is complaining both ways. But it is so easy to just lose patience and call those who don't share enthusiasm a troll. From what I understand, a troll is somebody who, perversely, posts in a forum for the sole purpose of angering reasonable forum members.
But what I'm reading in this thread, for the most part, is understandable frustration, skepticism, and concern. You might not agree with such sentiments, but people spending thousands of dollars, sometimes unwisely in terms of their own budgets, get emotional, cynical, and even bitter. If they are posting simply to express their feelings (and I'm seeing quite the surge in newer members since the EOS R was released), are we to just call them all trolls--without even engaging first to find out what their actual issues might be with a Canon releasing a 75 MP before, say, a best in class 40-50 MP? (Maybe Canon has discovered the Holy Grail of sensor tech, who knows?)
Now if I tell you that it would be nice if Canon made a dSLR as good as the Nikon D850, would you call that trolling? I don't think it is. Yes, Canon makes calculated, clear-eyed business decisions that have kept it the leader, but, as a customer, I can't help look at the competition and think to myself, I wish Canon made one like that. So, while I support the development of higher resolution bodies and lenses for those seeking such specifications, I'd also like to see Canon addressing the desires of many other photographers who, like myself, aren't seeking more MP at this time.
Is it rude to say, "Hey, what about me? My photography desires deserve priority!" while in a thread about rumored gear a member doesn't find appealing? In a way, yes, I'll grant you that, dak723. But it's an open forum with relaxed rules about staying on topic, and people react with their first thought, little filtering. I don't think it is helpful to just classify such posts as trolling, because, one, they are not, and two, it doesn't help the thread, the person posting, or the general feeling of goodwill that CR manages to maintain better than many other sites.
Just my opinion!
