Yes, they apparently have crafted the advertising to not be technically deceptive. Is it an accident or coincidence that they put an electret ‘capsule’ in what looks like an LDC? That’s a marketing choice, so there’s clearly some intention there. As I said before, in this case we’d really have to know their intention to see if they meant to mislead (some) people. I would guess this was carefully crafted to not get them in legal trouble. If someone designed a car that looked like a Cadillac, but they put a Honda engine and transmission in it, they could probably sell it to lots of people if they didn’t mislead people about the performance. But a Cadillac aficionado would know the difference and likely be critical of it.
At this point, it really falls to the consumer to question what they’re purchasing. Caveat Emptor.
Yeah, some people have been critical of that too (MXL), though at least it’s an actual condenser capsule and not something else. AFAIK all of this stuff is related to Chinese made products, and the sellers are perhaps less worried about reputational backlash, relying instead on price point. Interesting adaptation you have there, with the pencil mic.
