The stupidest thing about this claim is that it is totally irrelevant to Ericson, because all their competitors will have already bought/sourced and competely reverse engineed their commercial products anyway!
I work in the car industry, all the manufacturers buy each others models and tear them down and reverse engineer them as soon as that product is released onto the public market. For example, Ford release the latest Focus, and VW simply walk into a Ford dealer, and buy one, take it away, and carry out a complete "competitor bench" marking exercise on it. The cost of the car(s) is irrelevant, compared to the cost of the teardown study anmd reporting. I've even seen some of the big OEs buy competitor cars from dealers, and crash them to learn how they perform for example.
So the fact that someone on youtube has shown some (minor) details, which frankly wouldn't enable anyone to actually engineer anything, is totally irrelevant. Once the product is in the public domain, then unless it's "Uniqueness" is covered by patents, preventing someone else profiting from those details, it's fair game...... (and as mentioned those patents don't prevent the investigation, discussion or education of those details)
