Would it alter and/or affect certain features they have? Like, telegram with their so-called super encryption (although I doubt its secrecy these days as I witnessed one specific group has an admin that can pull your numerical ID and the dates of your account creation), or others?
I am careful with the term "alter" as it indicates manipulation of the companys code and violation of TOS, but since Telegram could run on top of the framework layer, there would be a lot more communication alternatives which provide more features than using Telegram within their APP.
