As the other commenter noted, this is kind of a nonsensical article. I am not by any means a fan of Mozilla's decision on Ublock, it seems egregious and indefensible. But the convoluted logic of making Manifest V3 about Mozilla is completely emptyhanded, and there's no rhyme, reason, logic, or precedent suggesting we should make anything of their absence of a statement.
Also, this is especially nuts because Mozilla HAS in fact criticized Manifest V3! They just happened not to have done so within a particular randomly selected window of time.
My guy.... you linked to a youtube documentary about the questionable economics of gold and a blog post about an unreliable certification group associated with Rainforest Alliance. Not because of anything specific to gold or certifications, but... to illustrate the general idea that corporations can be bad?
The level of generality you have to zoom out to, to associate those to Mozilla, is the same level of zooming out typically used for Qanon conspiracy theorizing.
This is exactly the kind of thing that people make fun of with Six Degrees of Kevin Bacon. If you're willing to zoom out to six degrees, you can connect Kevin Bacon to anyone in the history of cinema. It doesn't prove that Kevin Bacon is personally connected to everyone in the history of cinema, but what it does prove is the frivolousness of reasoning from such stretched out connections. That goes for historical connections, but also funding connections, and, perhaps most importantly here, for conceptual connections. And I would venture that trains of thought hinging on such remote connections are a hallmark of fuzzy thinking, which is why it's terrible to go from "Rainforest Alliance bad" to "... and therefore Mozilla ad privacy is bad."
That's not to say one shouldn't be concerned about Mozilla's venture into advertising, but that this is a terribly incoherent way of showing it, that's as liable to produce overextended false positives connecting anything to anything as it is to produce any insight.
