Since when did the lotm community started having beef with the tbate community

I still can't get this debate ever since it started. Lotm fans are calling out tbate fans that they got a anime adaptation(donghua) before tbate.

Like how is this even fair😑. Lotm has books in 3 different languages(I believe). And tbate has non. Also tbate isn't even that popular as a novel and the manhwa is arguably more popular.

So can someone explain tf is happening
