I am not a highly educated man, so Free speech, freedom of expression and censorship are closely linked in my mind. When I was young there was no internet, and less than a dozen radio and television stations. Although the government made laws to limit free speech, the media also applied censorship, often to protect their own interests, but also due to "invisible" pressure from the establishment.
Stopping people from expressing a view, or discussing a subject, fits somewhere within this "freedom" spectrum.
Like all "spaces" on the internet, this forum can be described as a "private entity", but it still has to respect the laws of our government (...whatever shape that may be in come Friday 8th!) and it also has the right to apply censorship, for whatever reason, or for absolutely no reason.
However, this forum does invite and encourage people to post questions, offer support to others and express their views. I haven't read the terms and conditions, but I'd expect it to suggest that users steer clear of a range of topics which might fit under the general heading of: sex, politics & religion. If there is also a RaspberryPi taboo list, I guess I need to read it.
The original subject (Raspberry Pi 3) is of no interest to me. I find this topic boring and rather naive, but defend the right of others who probably like to speculate about such things and swap specifications.
I'd also like to point out that the person making the Pi3 post only joined the forum a few weeks ago, and has already had a thread locked. What kind of impression has that made on them?
Unless there is some kind of bandwidth or storage space limitation, I cannot see any plus points in locking harmless threads. However I can see a few negatives, the most serious is that you may squash someones enthusiasm.
