Your cell phone provider almost certainly will respond to a valid warrant and wire tap your non e2e encrypted phone call.
I'd be very surprised if the most common mode of remote communication in any time period was not subject to government interception in some format within a short time of becoming such. That includes physical mail, telegrams, landlines, cell phone calls, txt messages, emails, etc.
Referring to "how things used to be" is not in fact helping the case for privacy.
