Yes. That is how I view them, and a fair description I think.
When I was willing to spend time on this (home networking + cameras) I would have never touched this equipment. It was all open source / cheap stuff with BSD or Linux routers, random switches, home assistant raspberry pi's connected to USB cameras. It would take some time maybe not a lot, but enough, and it would break frequently enough due to some update somewhere or something.
It's hard to not notice the ... ubiquity of praise for their gear over the years, but I haven't seen much clarifying what sets them apart. Maybe I should look at them like peak Apple but for networking gear?
