Sure!
I was merely trying to raise awareness for the need to bring privacy protection to a level beyond E2EE, although E2EE is a very important and useful step.

Yes, like Signal!
Which does not only use end-to-end encryption for communication, but protects meta data as well:

Signal also uses our metadata encryption technology to protect intimate information about who is communicating with whom—we don’t know who is sending you messages, and we don’t have access to your address book or profile information. We believe that the inability to monetize encrypted data is one of the reasons that strong end-to-end encryption technology has not been widely deployed across the commercial tech industry.

I haven’t verified that claim investigating the source code, but I’m positive others have.

Signal doesn’t harvest, use, sell meta data, Google may do that.
E2E encryption doesn’t protect from that.
Signal is orders of magnitude more trustworthy than Google in that regard.
