Have you been sleeping under a rock for the last 15 years? If the government wants to listen to you, they’ll just use the microphone in your pocket. Or better: they don’t listen to your incoherent ramblings and go straight for your search history, which is much more interesting than what you are generally talking about.
I don’t know if you know this, but it’s pretty easy for someone to make private their phone, search history, etc. You just need to be a little dedicated and sacrifice some usability.
You cannot do the same with microphones listening everywhere that you do not own.
Have some sense.
That’s what you think if you haven’t worked in the Telecom sector before.
Unless there’s something beyond switching DNS, using a VPN and your own router/modem. It’s maybe 100$ up front and ~3-5 per month to be able to circumvent any telecom.
