Not really. There is a difference between expressing an opinion and declaring that your opinion should be the ruling factor.Well we are all "imposing our own viewpoint" merely by making comments on a forum...
"...I feel that manufacturers also have a *responsibility* to ensure that their products are fit for purpose. And IMO, a stills camera without a viewfinder is not fit for purpose, unless that purpose is to produce technically poor and badly composed snaps."
There is not a lot of space between that statement and "I don't like it, so therefore they shouldn't do it."
Everyone on the forum is expressing their own viewpoint. But expressing that viewpoint is not the same as declaring that your viewpoint should govern how others behave.
People are free to make choices, including bad ones.
And, apparently Canon wants to give people choices. However, "bad" is subjective and what is "bad" to you may be "good" to someone else.
As I've already said a number of times, I'm not interested in a camera without a viewfinder. I just don't begrudge Canon for offering one, if indeed they do.
