What does rile me up up is deliberate attempts to deny me (and others) access to the information that I value. There are some here who repeatedly seek to disrupt, sidetrack, derail, and shut down conversations about topics and products that trigger them.
I have to agree with you. I have seen a discussion where the OP asked about a certain product, and a few posters sidelined that product and started discussions on a totally different product. Sad situation.
But I don't think anyone denies to provide information - in fact of late they provide over information - which might be completely irrelevant to the original post. I think based on this alone, someone started another thread that started doubting if people have "agenda" when they make posts or start a thread. It's an open forum and things are bound to happen. If the posts stay relevant, then that would be the best approach.
