Telcos are complicit in the crime because they know they're going to make money no matter what. Everyone is paying for 4G LTE and 5G now, and that's not going away. Why bother fixing the legacy phone system when it still brings in extra cash the way it is?

I for one have had calls disabled on my phone for a long time. Couldn't be happier. AT&T, Tmobile, etc... it didn't matter what carrier I had, they would all tell me to install some 3rd party app to block "unknown" calls and robocalls. Absolutely ridiculous.
