I don't think HK get the same treatment as Hobby Boss or Trumpeter.
Hobby Boss and Trumpeter have a very busy release schedule; produce kits with many minor inaccuracies regularly, some howlers every now and then and some very accurate kits which usually arrive with little or no comment. They have a reputation.
HK on the other hand have a very small catalogue, they have a reputation of releasing generally accurate kits sometimes with innovative design features. However with the Mosquito they dropped a clanger with the front half, some very obvious mistakes which totally spoil the look of the model and are nigh on impossible to correct. However, thankfully for the consumer it seems to be a one off.
Personally, I hate building the things, I find it a chore, a necessary process to get to the fun bit. Usually I'll ignore inaccuracies (normally I don't know the subject anyway and it looks good to me so I carry on in blissful ignorance), maybe I'll fix something which only takes a few swipes of a sanding stick if I've been made aware of it as most of the time I wouldn't know what was wrong. This Mosquito is a totally different problem, the shape of the nose for example is so far off, it's so obviously borked that it needs entirely scratch building and a new canopy if you want to correct it. I've not seen anyone attempt it yet! Mind you, many people will just build it as is, enjoy it and be pleased with the results.
