Copyright laws are complicated and the consequences of infringement can be devastating.
Manjaro as a company has from the beginning been separated from the Manjaro distribution but as more and more consumer targeting entities partner up with Manjaro GMBH - the legal concerns become more present especially for entities located in the US.
The european copyright laws is very strict and there is very little room for interpretation and this is likely a concern for entities using Manjaro through their financial transactions with Manjaro GMBH while supplying the operating system to end-users directly.
The approach Manjaro Team has taken - although not in favor of the community - is a better safe than sorry approach and while it may be undesirable in some aspects - it is an unfortunate consequence of software patents.
There isn’t really much to do if you want to play it safe - I can only respect the team for their decision.
Arch Linux on the other hand doesn’t distribute anything definite as the end-user is completely in charge.
Therefore - with an Arch system - there is ever only one responsible for any give system - a single person - which has bought the hardware and likely is covered by that - unlike the mass distribution of preinstalled systems - which represent a completely different entity - copyright wise.
So while I can understand the annoyance - the entities partnering with Manjaro GMBH has a legal concern - which Manjaro GMBH has to address and the only logical way to address it is to adhere to the copyright laws. Until some entity take the legal rounds required - which requires an excessive amount of cash - I don’t think Manjaro GMBH has a choice.
It shouldn’t have an impact on the community but ripples - you know - a butterfly in Calcutta …
Technically yes - if you have the hardware to go with it.
And while we are at it - again this is the end-user choice and has no relation to Arch or Manjaro as an operating system.
No - the end user always have a choice - the problem is redistributing - as in facilitating the usage of copyrighted software 
I hate that phrase … It is like - if you could possibly have a similar idea and implement something similar - my patent beats your brain .
As such - if you have bought the hardware you are entitled to what-ever that hardware offers.
