Rack-A-Tier cable support

Why are Rack-A-Tier and other brands of cable support not permissible per NEC code.
They would be supporting the home runs of 12/2 and 14/2 NM cable and would be mounted on (not below) and running parallel to the basement joist.
The installation is extremely messy, these would go a long way to help cleaning it up.

in the reviews on amazon.
"These are not UL and inspector approved. I would not recommend,"
"NEC Code violation. 334.12 (C) can not be used if smaller then two #6 or three #8 . 12-2 and 14-2 type NM Cable (romex) can not be secured at angles with joists in unfinished basements and crawl spaces"

The website states they are listed by ETL and meet UL standards.

If installed in a basement or crawl space on the bottom of floor joists you could use them, however you would likely need running boards.

is no 334.12(C) in NEC 2017, 2020, or 2023.
This device will allow for cross joist attachment without the need for a running board, no different than drilling thru joists to support cable.
If this is quoted from a review on amazon would only believe half.
in fact 334.30 Securing and Supporting. would allow if meeting requirements shown:
"Nonmetallic-sheathed cable shall be supported and secured by staples, cable ties listed and identified for securement and support, or straps, hangers, or similar fittings designed and installed so as not to damage the cable,"

I think the amazon quoted the wrong section. I think they meant 334.15(C).

(I am not commenting on if they are or are not allowed. Just wanted to clear that part up)

I should also add that they put "Accepted by IEAI" when they probably meant IAEI lol.

Their installation video shows the use of running boards when crossing joists or rafters.
That looked like an attic, which would be on the top of ceiling joists. I didn't see a video for beneath the joists, but I saw some still pics of beneath the joists. I didn't see running boards there.
