Over the weekend, AMD said it planned to do just that in a firmware update scheduled for release next month. More often than not, the chipmaker refers to TSME as Memory Guard.

“Regarding certain non-PRO Ryzen 9000-series desktop processors, a BIOS option to enable Memory Guard was previously available but was removed in a recent update,” AMD said in an email. “Based on valuable community feedback, we will reinstate this option in an upcoming BIOS release in July.”

The company has yet to explain why it removed the protection. Critics speculate that AMD dropped it in an attempt to steer customers toward more costly CPUs.

It’s possible, though, that there were less nefarious reasons, such as the difficulty of continued support as chip designs changed. Another possibility is that AMD made the move for performance reasons. Encrypting and decrypting data in memory creates latency. Slowdowns are the enemy of gamers, one of the more popular customer segments using the 9000-line of Ryzen processors. Since many gamers already voluntarily disabled TSME and had little need for it in the first place, AMD may not have considered the change of much consequence.

The incident, and AMD’s refusal to discuss it, is emblematic of the public relations landscape that has emerged over the past two decades. Once, Big Tech and corporations in general were willing to acknowledge service and product changes to ensure customers had a predictable experience. They also showed a willingness to admit mistakes and to say how they planned to do better. Now, there’s only silence. As the companies’ power and dominance have mushroomed, their sense of accountability has diminished proportionately.
