I wasn’t expecting to find a whole conspiracy while trying to fix my Deck, perhaps the memo is a hoax or something, but this all just lines up so naturally.

My experience is that it is intentional, just like countless other examples of monopolistic anti-competition behavior. Especially with gaming, where a duopoly of video card manufacturers has spent the last several years intentionally crippling virtual GPU support on consumer-grade hardware. There are many others to blame though since Windows is designed to collect as much telemetry as possible, making it near impossible to fully disable its collection. There are entire forensic analysis toolkits dedicated to the troves of data that Windows stores on nearly every activity you perform. So while Microsoft's actions may clearly violate antitrust legislation, the intelligence agencies saw Microsoft as their biggest ally & worked to help them maintain the status quo.
