Hi,

so that's certainly debatable.

Apart from the privacy aspect though, tunneling all traffic through an operator proxy that would otherwise not be in the path certainly can have performance and management aspects. It's probably going to add delay due to route stretch and possibly queueing, and can limit throughput due to processing overheads or overload.
