The experience is way more consistent in a centralized service. In Skype, sometimes your messages took ages to send and the call quality was horrible.
In turn, on a centralized service, they have limits, monetization, and they can sell your data.
P2P exposes your IP to those you need to connect to. So if you're a streamer or something - share a file and you dox yourself. It also means if you're offline you can't send the file.
It's just not practical over remotely hosted for it to be the default. There's other apps you can download if you still want to use P2P
That's the main reason I left Skype. Giving someone even your username and simply answering their call would expose your IP and be a major security liability.
Almost as though it would be better if it didn't
Pros and cons.
