I'll add a brief note of dissent, as it could (hypothetically) help someone (and some people do haunt these forums looking for help) --and I'm aware that very few people have the experience with the languages (or the fieldwork) to even offer a casual comment on the subject.

Vipassana is mistakenly taught as just a mere method. It arises straight from the world view of Therv[ā]dan Buddhism. And in Buddhadharma it is postulated that everything arises from a chain of causation.

No, it doesn't come straight from anything: it's the product of a number of 20th century impulses, and has a much weaker connection to anything ancient in Buddhism than it does to
(surprise?) fads in Burma that were current at the time of its founding. This isn't surprising in itself, for the same reasons that (e.g.) America's "Zen Master Rama" has more in common with fads in his own era (in California) than he does with the first patriarchs of Zen Buddhism (in China).
Goenka wasn't the only one innovating and calling it "ancient" in his cultural context: plenty of the stuff (e.g.) that Mahasi Sayadaw taught has no basis in any ancient scripture (and, in a sense, that's okay... so long as nobody's deceiving themselves about it, nor being deceived).
Almost nobody knows anything about the ancient sources to (thus) be able to critically compare them to the modern practices. The example you've mentioned in single phrase, "the chain of causation", is one of the most laughable examples of gross mistranslation and misinterpretation in Buddhism today…

…although the most laughable might be the mistranslation of "breathing meditation" itself.

These are not minor errors of interpretation: for many of these groups, these are core doctrines, that define "orthodoxy" from their perspective. They're also wrong --and not "a little bit wrong" but all the way wrong.
In over-compensating for their lack of any kind of scriptural basis, they get into a cycle of attacking anyone who would debate these assumptions with them. That's sad for a number of reasons, including the fact that Buddhism was founded on a compendium of debates, and is supposed to be a religion of philosophical debate; sadly, these groups (whether they're considered cults or not) take on an aesthetic of hyper-conformism, because debate of any kind has become impossible for them.
I have no reason to say that Goenka is the worst of the bunch; however, what he's teaching is not orthodox Buddhism, and actually has a somewhat difficult dotted line connecting it to Theravāda Buddhism… and many things that be pointed out that separate Goenka-ism from Theravāda Buddhism (including its peculiar anti-clericalism: Goenka's movement consists entirely of laypeople doing things for themselves, and not working with monks living under the Pātimokkha, etc.).
I believe in freedom of speech, and, basically, I think it's inevitable that people will invent all sorts of nonsense and (falsely) attribute it to Buddhism; unfortunately, right now, there is no "other side" to the argument. There are virtually no legitimate sources to compare any of this stuff to (and the most diverse and dishonest nonsense imaginable, even about the subject of meditation, can be found with the imprimatuer of someone-or-another's PhD stamped onto it).
Both Goenka's group and the Dhammakāya group have founded "research institutes". It remains to be seen if any of them will proceed to do legitimate research
(not impossible, but unlikely). Sadly, we now have a long list of failed institutions founded in the 20th and 21st centuries; none of them remained operational for long, and very few were ever productive of scholarship.
