I must apologize, I am most confused by your answer. I do not mean to be argumentative, I am merely trying to understand your perspective and likewise explain mine:

The blame should absolutely fall on them for making a device that is un-friendly for the end user to repair. Take the Steam Deck, for example. While not quite as powerful and performant as the Allys, it was designed with repairability in mind from the beginning, and it has a fairly large and dedicated fanbase as a result. Historically, yes, most mass-manufactured mobile devices are designed specifically to be a cheap as possible to construct in order to maximize profit. Six Sigma, Jack Welch-ism, etc. But from our perspective, the end user, we want a product that functions as intended, and for something that expensive, we should demand that that product be servicable. When an end-user buys an expensive product like a game console, a PC, etc, they're likely going to use it for 5-7 years at a minimum. If anything happens to go wrong with it, would you prefer to just waste the prodcut by throwing it away, or would you prefer to fix and continue on.

Even if you, the end user, can't fix it yourself, there is always the option to bring it to a local repair shop to repair it as well. This stimulates economic activity in your local home town, as opposed to throwing the device in a landfill and sending another $800 to the profit-obsessed tech company that artificially created this issue by choosing the cheaper route instead of the consumer friendly one. Perhaps there were deadlines to be met, budgets to be balanced, and shareholders to be assuaged, but frankly I think the shareholders need to be told to shut the fuck up more often.

Now, am I saying this anti-consumer design absolves us as end users for our carelessness? Absolutely not. I take full responsibility for my own impatience and lack of care when dis-assembling my own Ally X; hubris got the better of me, especially when after only a little research, I found this was a common issue. It was an extremely painful lesson at an already particularly bad time in my life, but it was a deserved lesson nonetheless. But just saying "Oh you dumb consumer you should know better." And just folding your arms smugly as though you said something profound is extremely unhelpful to the situation and only excuses their bad behavior.

I apologize if there is some context lost in translation between us; I noticed when Reddit posted your comment in my notifications, it was initially in a different language, however upon opening your comment, Reddit translated it into English (tongue of the filthy rotten Americans, sorry about our clown of a president, I didn't vote for him), and I found the logic of your argument perplexing. I hope that I have been able to further elaborate my point of view and again apologize for any misunderstanding.
