It's a project that offers support via IRC, the average internet customer/consumer is not the target user base.

I think they point here is, they make it obvious that they don't want to support JS,CSS, etc... The support for other protocols is the same thing - neither a finger page, nor a gophermap need css or JS.. So if you want to use it with the part of the web that requires those, this is not for you. It's a tool for those who use a different part of the web. Those who only need a TV and not a circus. One might see a commentary about the state of the web in the project, but not necessarily - it's just a tool for those who have a need for it, e.g to browse the intranet for a research institute.. if this browser is all you need for that you greatly reduce the attack vectors on your institute among other benefits.

Given that customer expectations of TVs now include being normalized to TVs getting slower with updates that cannot be avoided without jumping through hoops, sometimes even bricked, and occasionally even showing ads because the company you bought it from decided they needed to extract more wealth from you, that is pretty spot on. But perhaps not how many people think it is.

Which they're also not trying to do. It's just a cool project, shared for those that want to use it.
