This is hardly surprising if you consider many telcos are terrified of becoming dumb pipes and rely on traffic inspection (and zero rating) of various kinds to manage access to things like media streaming services (which they throttle), their own self-care systems (which rely on manipulation of HTTP headers in transparent proxies rather than doing authentication in a truly secure way) and keeping track of DNS requests for profiling (there are a lot of privacy concerns that telcos skirt every now and then for the sake of “securing their network”).
So it’s no wonder they’re throwing up FUD, lobbying and outright blocking the service due to “technical limitations” rather than letting customers use it and bypass all the spaghetti they put together since the WAP days of walled gardens.
It’s not going to be a nice, happy little service roll-out, and the telcos will never own up to being on the wrong side of the matter–or of history.
