This is needlessly splitting hairs, Linus Tech Tips is absolutely part of the tech industry, and the parallels to other horror stories of the tech industry are too great to ignore. The people working on these videos are tech professionals similar to yourself, they test software similar to what you make, they have a company culture similar to tech startups, and other tech professionals consume their videos giving them influence in the tech community. They may not be doing the same thing in the industry as you are, but that doesn’t mean they aren’t part of it.
