LUA is a programming language used primarily for scripting. In the context of Logitech devices, these scripts allowed users to automate tasks through automatic scripts. Some users reported Logitech devices’ enabling of LUA scripts as the main reason why they purchased Logitech devices as opposed to other manufacturers’ products.
Some users had been experiencing issues with Logitech’s G Hub’s support for LUA scripts over the past year, and these issues culminated in a January 13 software update that seemed to fully break GHub’s support for LUA scripts, leading to users being unable to save any LUA scripts that they had worked on, leading to the loss of substantial amounts of programming work.
Logitech did not officially acknowledge the issue until January 19, 2022, and on January 26, 2022, Logitech finally pushed out an update with a fix to the issue, but it did not restore the programming work that users lost due to the January 13 update.
A similar lawsuit was filed against Microsoft in 2017 regarding a software update that caused users to lose data and damaged users’ devices.
Claims arising from Logitech’s software and products are subject to binding arbitration as per their EULA.
