A recent WiFi vulnerablity, https://www.fragattacks.com/
> The discovered vulnerabilities affect all modern security protocols of Wi-Fi, including the latest WPA3 specification. Even the original security protocol of Wi-Fi, called WEP, is affected. This means that several of the newly discovered design flaws have been part of Wi-Fi since its release in 1997! Fortunately, the design flaws are hard to abuse because doing so requires user interaction or is only possible when using uncommon network settings. As a result, in practice the biggest concern are the programming mistakes in Wi-Fi products since several of them are trivial to exploit.
There's no need for everything to be lowest-common-denominator. Product management is not statistics, it is aspirational leadership for upward mobility in human values, including but not limited to function, form, and creative power. e.g. a tiny minority of humans create art for millions, yet both can use the same device + accessories, if devices are not neutered.
