I mean, there are literally professional fields of practice and study around operations and project management. And let me tell you, those fields don't say "take as much money as you can upfront and figure out fulfillment later." This isn't the evolution of a successful business, it's a company with significant growing pains that haven't been resolved. I say this as someone actively working in the field with multiple certifications and years of experience, so take your gatekeeping elsewhere.
I don't think LRG should get credit for doing the absolute and bare minimum by eventually delivering a product that's mostly correct ("mostly" being directed at snafus like Game Tengoku, "signed" vinyls, etc.). Doing any less is probably cause for fraud cases. The fact of the matter is, they're bad at this aspect of running a business. Different companies and different consumers place varying degrees of value in it (which is why there are two sides to this argument to begin with), but saying "another company is worse" or "other companies are bad too" doesn't absolve the real issues they have here.
Also, I think the reason that it's important to keep having this conversation is that the issue is getting worse. They haven't had a break week for over a year now and their production backlog has grown from ~100 items at the tail of 2019 to nearly 200 now. You can like LRG if you want. You can continue to support them - that's completely your right and your prerogative. But acting like everything's fine and the criticisms are baseless is disingenuous.
I just don't agree with you that the approach of "take as much money as possible" and "figure it out later" is the approach they are taking. There are a lot of people here that have professional degrees and strong feelings about how businesses should operate. None of them own or work for LRG, so their opinions are valid, but frankly irrelevant.
Are there ways that LRG could simplify their business by reducing the number of products, eliminating the unique packaging and elements of each product and simply going back to a truly limited model where product is ordered well before preorders open? Sure, but the significant down side to that is that there are very few other companies that could or would pick up the slack. As a consumer and someone who strongly prefers physical media, that means many of the games that LRG has made and will make available will likely never exist as physical products. Similarly, a company like LRG can't maintain and pay a living wage to a full-time shipping staff, customer service staff and marketing and design team as well as all of the other overhead departments with a model like that.
There are plenty of companies that do take that minimalist approach, including Super Rare, Hard Copy Games, Strictly Limited and Play Asia/East Asia Soft. It's fine if you only have a couple of employees or your limited company is part of some other retail or business enterprise, but it's not something that lends itself to growth or the ability to work with large companies like Ubisoft and others.
I get that there are significant delays and that LRG's windows are largely a joke. I also get that they have had a couple of products where they never delivered a promised fix like the DLC you mentioned. At the same time, out of literally hundreds of products, there just aren't that many examples of problems and certainly, I am presently surprised that as far as I know, they have never had a truly defective product ship to customers.
As for the need to constantly discuss their flaws, if this was four years ago, I would agree. A lot of people didn't have notice of their shift in model or the lengthy delays that were likely to follow. We are now years in at this point and everyone is well aware of what they are buying when they purchase from LRG. If you really feel the need to share feedback, why no go directly to LRG's Twitter or Facebook or one of the forums where they do still interact? What's the point of constantly posting in a thread on a deal site where everyone is either still an active LRG customer or a former customer?
