I wish there was a dislike button. Who are you, and how much 1st hand experience with VB and other frames do you have?
Saying there is "no quality control whatsoever from velobuild" is simply false. I don't even want to argue, I just wish posts could be downvoted.
I'm sorry that you feel butthurt. It would certainly help the conversation if you could bring yourself to argue your point. Have you audited their production to know they are doing any QC? Are you sure you aren't conflating quality with quality control? In general you don't necessarily need any of the later to produce a decent product...
I've bought two frames from them, one perfect as you can only wish for, the other had a fork steerer tube that was 2mm(!!!) out of round, oval oversized pressfit BB (so you can't press in anything because you can just pull it out without any force), threads of the brake interfaces filled with resin, a seat tube that was only reamed out to about 7cm depth, voids on any machined surface and flaking paint right out of the box (that it wasn't painted as agreed upon should be a given at this point),.
The issues of that second frame are so obvious and present through the whole manufacturing process that I can't imagine even a rudimentary QC process to miss ALL of them and not pull that frame at some point from the production line before it reaches a customer.
I've audited enough production places to know the theme. They aren't evil, notice the defects and send them to the customers anyway - they just don't have dedicated processes set up so a defective product can be detected and pulled from the line at a later stage without incuring penalities to the person reporting the defects.
QC is a significant "non-productive" share of the production cost. If you can cut that, you'll be able to offer the product for cheaper. If your production is set up well in general, so the defect rate is low, you might even come ahead in customer experience on average.
