Skype video and audio it's crippled with speed to such extent it's unusable for most of the time so yeah, technically you are correct, it's not blocked, it just doesn't work which is de facto same thing for end user deciding what app to use lived in China for many years, it was frustrating I could not talk with my family abroad, apparently too dangerous for Chinese Gov to let me talk with my parents and I am not gonna ask people outside China to install spyware like QQ or WeChat. the saddest part it's unless you wanna completely cut the ties you still need to keep it installed like my wife does (I cut the ties with non VPN folks), any other reasonable option would be freezing and unfreezing on demand which kinda ruins messaging experience and might as well use email
