What tends to happen I reckon is that the end user runs it into a cheap antenna or mismatch and nukes the LPF, something which can happen to a $500 Yaesu HT if you're an idiot.
But the gatekeeping is strong in amateur radio. Annoyingly so.
$10k iComs are mostly unicorn poo, with exception of somewhat useful DSP filtering, for which the real cutting edge research in radio tech is said to be used.
(Back then, ham radio software was also consistently proprietary payware - in an area where every participant would have benefited so much more from an open source approach, as you could expect actual contributions - and software-defined radio was the devil, at least that was the impression I got.)
As for open source, this was probably the original open source. Lots of people build their own radios and still do and publish the designs for nothing. There are technical journals such as Sprat which cover this on old fashioned paper form. Software is mostly open now from what I have seen. Main tool these days for digital modes is a good example http://www.physics.princeton.edu/pulsar/K1JT/wsjtx.html - some people are using this with home build SSB transceivers and computer interfaces.
I've got an FT-60 and FT-818 as well for ref.
Wouxun are very good Chinese radios, with analog RF front-ends and very sensitive, but the price is in the same order of magnitude of the Japanese.

However, most reports are from a few years ago. So I was curious if Wouxun changed the module in newer modules.

Indeed, there are repeaters out there who's owners have "banned" Baofeng operators[0] since they believe the radios aren't legal (due to high spurious emissions[1]) underamplified microphones, poor output audio levels, and clicking noises, and that their low cost is undermining "real" ham radios. They can be uniquely detected through fingerprinting [2] (typically by looking at it's carrier frequency drift during the first few seconds of keydown).
No, this is just using a Baofeng transmitting the output from an mp3 recorder using an Arduino-powered relay to key the radio. This is also known as foxhunting[3], and it's a lot of fun!
