Since MacBooks do not have cellular modems they rely on an iPhone to forward SMS/RCS text messages. You cannot send a text message to non-iPhone users on your MacBook without the assistance of an iPhone.
So do you have an iPhone signed into the same network and Apple Account as your MacBook. Check the following settings.
On your iPhone->Settings->Apps->Messages->Text Message Forwarding->select your MacBook
iPhone->Apps->Messages->Send as Text message ON
Also make sure RCS messaging and MMS Messaging are both ON

And could you please cease with the conspiracy theory about being punished by Apple. Knowledge is better than ranting.
