I didn't take time to every lengthy post about why crafters deserve to keep HQs or whatever. I do agree crafters deserve due credit for taking the time, money and effort to skill up to 100+ and their subcrafts in that they can achieve the ability to make the items they sought to make.
But as a business it works both ways. Customers seek a provider of service to create a sought item they wish to receive (HQ or not). The crafter creates the basis of circumstances for when they either break, NQ, or HQ. The crafter can decide to say "tough beans" when it breaks, give them the NQ (assuming customer is the supplier of mats), give HQ or keep HQ and repaying for lost mats.
I may not have any crafting experience, but I find it pretty silly for anyone to berate someone based on their choice of business etiquette or the customer's level of expectations. Every crafter is their own seperate branch of business from everyone else. I for one find nothing wrong with charging for service based on frequency/quantity or HQ results. Nor do I find a problem with respecting the customer's given results from their purchased materials, be it HQ, NQ or break. It all depends on how one wants to do business, but don't shun others for how they want to do things when it's their own personal business and achievement that they are free to use as they wish.
The only thing this separates is the motive one has behind crafting. Some do it strictly for money, some do it to provide open service to all, some do it for themselves, and some keep it close knit to have synth access to friends or an LS. Whatever the choice(s) may be, it doesn't make anyone wrong or stupid.
Edit: That being said, I do agree that the high end items that are extremely rare and took ridiculous amounts of time, money and effort to get to the point to even remotely have a chance of creating do at the very least deserve a mutual amount of gratuity or an agreed circumstance to keep HQ in the rare chance it is made.
