Cant read the article due to paywall, but, nothing "went wrong" with skype, it was and has always been utter trash. Just having your username leaked was a security breach. Skype's only merit was it was the first easy to use video calling platform that combined text, audio and streaming in one.
Theres a reason why it was so easy to move my friends group off skype to discord right when discord launched, but I havent been able to convince that same group to move from discord.
For my sanity, it has to be satire
Thats what it stands for, yeah. Theres not any erp in the game. The poster above you references not liking kira (the game dev) because of something early access they dont want to explain about. I could be off on my timeline, but iirc thats about when they added pronoun options for the characters.
Doesnt like the game? Thats fine, despite it being my favorite indie game of all time I do think its niche. But I wouldnt hold this posters views with any merit.
My memory says that both vent and teamspeak were way better for audio, but this was also a time where no one had a mic remotely close to the average you get today. Video, yes. But skype was really buggy and often did not even work
