While I would choose a less abrasive way of stating it, I agree with your underlying assessment. At the recommendation of basically every networking forum and subreddit, I bought some Ubiquiti stuff to power networking and wifi for a new place I recently moved into. It cost 3x what a mid to high-end Linksys would have cost, and as far as I can tell provides literally negative benefit for my purpose:
Specifically, rather than a single box and an easy interface, I now have 3 devices that all require their own power bricks, connected via Ethernet cables, and a UI that required reading all sorts of documents and tutorials just to mimic the functionality of my last consumer-grade router. Not to mention the wifi coverage isn't even as good as my old router, even when adjusting a bunch of settings from default based on said tutorials.
I'm not saying that this hardware isn't worth it for some people, but for anyone who uses it for regular streaming and remote working, it's completely not worth the expense, hassle, and inconvenient form factor.
