Do form control check boxes "do" anything in word (or anywhere)

I am making a word document in which I was using activeX check boxes to hide text when its unwanted.
(For context, it's a receipt that sometimes needs certain disclaimers and sometimes doesn't)

But, for reasons best known to Microsoft it sometimes turns my activex checkboxes into images making the document entirely useless
(I did look into this a bit, but from what I can see I just can't risk including them if they are just gonna brick)

Some sources say form control is fine for simple tasks, but also say they can't be used in VBA.
Articles like this :

NO LINKS ALLOWED FOR NOOBS

Is that seriously all they "do"? (Nothing)

I see people saying they have uses but I can't find anyone using them for anything.

I've not really used VBA features in word, though I have in excel and as far as I know its never turned them into images so I never needed to look into form control.

Can they make text hide?


Side note, is this really forcing me to attach a file to post?

You do not have to attach any files to post a question; but, you attached an excel file for a Word question?

I was confused by the banner at the top of the page HOW TO ATTACH SAMPLE WORKBOOK.
Thought it was saying I had to attach one to post. didn't see the actual error beneath it about links/images/videos for new users.

the one that isn't an error is yellow and sticks out, the one that is a error blends with the rest of the page.

and "edavidson6, Fast answers need clear examples" sounded like I needed a attachment to post.

Sry, figured it out now.
