I think everyone on the team should get involved in this kind of feedback because raw first impressions on new content (which you can only experience once, and will be somewhat similar to impatient new users) is super valuable.

I remember as a dev flagging some tech marketing copy aimed at non-devs as confusing and being told by a manager not to give any more feedback like that because I wasn't in marketing... If your own team that's familiar with your product is a little confused, you can probably x10 that confusion for outside users, and multiply that again if a dev is confused by tech content aimed at non-devs.

I find it really common as well that you get non-tech people writing about tech topics for marketing and landing pages, and because they only have a surface level understanding of the the tech the text becomes really vague with little meaning.

And you'll get lots devs and other people on the team agreeing in secret the e.g. the product homepage content isn't great but are scared to say anything because they feel they have to stay inside their bubble and there isn't a culture of sharing feedback like that.
