You are failing to understand the reason they were posted in the first place.
Cruz and/or his campaign posted the raw footage on the internet so that his pacs could use it in ads for him.
Since it is against campaign finance law for the campaign or Cruz to communicate with the pacs this is their way of getting around the law.
Cruz films subject matter that could be edited to use in ads, posts the raw footage on the internet, the pac or pacs then go tho the internet, pick up the footage, edit it, and put together ads they will use to the benefit of the Cruz campaign.
Like I said, I’m sure the other campaigns with pacs do the same thing but the reason it is done is to get around the law.
I know that doesn’t fit with the squeaky clean image some have about Cruz but there is no other reason for him to have done it unless he just likes having unflattering video of himself and his family posted on the internet for anyone to pick up and use.

As described in your linked article, other campaigns did not post raw footage, but Cruz did. Please read your linked article.
