Macquarie/uts/wsu law graduates are employable and sought-after because of the skills the degree gives them. Firms look for those who are competent and a fit and proper person, not the 'prestige' of their university. Where reputation does play a role, it must be supported by a strong candidate who applied themselves throughout their degree.
It is a good thing that these institutions allow more people to study law. I don't know why anyone would feel threatened by making a notoriously inaccessible degree more accessible. This access matters particularly for those individuals who were never going to get a 99+ ATAR because of various inequities that the system will not adequately address. There are schemes that aim to assist with this of course, but they aren't perfect.
It is quite apparent that you have never studied law yourself, and it is unfortunate that you feel the need to discredit the hard work of all of those graduates who remained consistent and dedicated and who ultimately graduated with a law degree. Studying law affects the way you think, write, and speak, and these competencies are highly sought after by employers, regardless of where you have developed them.
I am assuming you are not saying this to be malicious, but I strongly discourage you from propagating this narrative. If you want to praise / critique universities, by all means, but use evidence with merit rather than vague ideas surrounding prestige and superiority.
