Generally, independent musicians aren't necessarily registering their works as they perform them, but that shouldn't take away from the trend that it's easier than ever to record and play music and that the production of music is rising.
This contradicts Lowry's observation, based on his wife's recording business, that music production has decreased. Musicians no longer have the budget to make professional recordings, compared with the past and also are less willing to invest in it as in the past, because it doesn't recoup costs because of piracy. They instead concentrate on live shows.
One problem in Masnick's report, as I see it, is that he does not acknowledge that the "technical giants" do well for themselves in selling music without passing the gains along to the musicians who created it. He touts kickstarter, as if it's a viable route for most of the musicians. He mentions bandcamp without saying its actual share in music sold.
I see no problem with Lowery establishing his credentials upfront. It allows the reader to understand his biases and also decide what statements can be taken at face value. For instance, I know upfront that the author actually understands what is involved in the process of producing a record and the process of making a recording. The same cannot be said of the majority of those posting on slashdot. For instance, I saw someone commenting negatively about Lowry's description of needing to position microphones, which takes time. The process of recording is still a labor-intensive process, in spite of the technical advances.
I think it is quite relevant to establish whether a report that he criticizes may be biased. Whether or not it rises to the level of "propaganda" or if you want a more politically correct term, does not matter. This is still relevant and from what I understand it is not stated clearly in that report and that site.
Pretty much all of your criticism comes down to presentation, rather than substance.
