All civilizations are based on a thin veil of trust. Law is based on the certainty of trust that underlies the application of justice. Once that veil is pierced, things go to hell very quickly.
Once upon a time, a fast food outlet had an owner who said something that was 1) legal 2) within his rights to say 3) controversial
There were some who felt so offended by this outrage that they decided that the company should be punished, if not entirely extinguished
Politicians across the country then worked to ensure that zoning laws were changed to ensure that this company was specifically targeted. Several large municipalities took action to ensure that this company could not even set up shop.
In the end, this company has ( so far) prevailed. But it didnt end there. But we see a new model of business being applied - Get woke, or go broke.
Parler is being removed from AWS because it is a place where the "unwoke" go to talk to each other. AWS has decided to act as a vigilante to the cause of wokeness and has decided that this business is worthy of being destroyed.
