Besides, this is not due to design, they are artificially and willfully imposing a time limit to the ability to repair a product for absolutely no reason other than to screw their customers. That’s ********.
You're assuming that. We don't actually know how Apple will treat vintage/obsolete Macs with a T2. Apple itself might not even know yet.
It also isn't artificial. It can be argued that it's a poor design, or even that it's deliberately malicious, but it's not artificial.
Even companies that "need and depend on the fastest and most powerful hardware" will buy the cheapest toilet paper available, because a penny spent is a penny denied the shareholders. That $10K Mac, and the employee who insisted upon getting it, will eventually stick out as wasteful spending.
By your logic, no company has ever had someone build an extravagant skyscraper for their headquarters.
