It's deeply concerning how attorneys like Matthew can remain active for over two decades while having no understanding of the laws.
Matthew is the sort of attorney who, most likely, has made his living being arrogant and obsessively stubborn, simply because he at some point, passed the bar. There is a saying amongst attorneys that 'it's all how you word it'. If you word anything a certain way you will win. So the laws and codes to this sort of attorney do not really matter. An attorney can spend his career with this sort of zealous style and win enough times to make a living.
The letter Matthew wrote was contradictory, did not take law into consideration, and was purely meant to be used as a bullying tactic rather than pointing out actual law violations or concerns. It was as if the letter was written by someone other than an actual attorney. Sentences were cut off, etc. It was quickly written without any care or regard to his client, seemingly, so he can make a quick buck.
