To give a bit of the backstory, Learning with Texts was a web application written in JavaScript which allowed for a sort of computerized reading of interlinear texts. However recently, Steve Kaufmann and LingQ have decided to threaten legal action against the software (in the public domain/Unlicense previously) to remove it from public circulation.
Do you have a source that confirms LingQ filed the motion?
It seems like the most likely explanation, but I haven’t been able to find much more context here outside of the update to sourceforge.
