Yes -- and companies or governments don't want to be _contacted_ by you. It's a cost to them. The median "contact us for a sales quote" form is clearer and has less friction than the median "file a complaint / ask a question" form.
One reason not in the article people might use forms instead of email is the "set and setting" of being a guest on a website and filling out their form. When in "your" email inbox as opposed to on "someone else's" site, you may conduct yourself differently.
An example of this is the sometimes-onerous Github issue template questions. I'm not arguing they're not necessary, but they do two things: mandate required information and _imply_ that you are a guest and you must hold yourself to someone else's communication norms.
