You're literally inventing conspiracy theories with zero evidence. Decreased performance on upgrade is an extremely common feature of most software. Servers, desktops, and smartphones are just computers running operating systems and applications. Upgrades bring new functionality, which usually has a cost in terms of system resources like CPU/memory. This is the primary explanation for "slowdown on upgrade" problems. If you didn't know this, you're probably not an engineer who works on these problems i.e. an expert. This is just one example of how non-technical people get themselves very confused and start inventing conspiracy theories.
