Absolutely agree. People change. I have changed a lot since I went down the Bitcoin rabbit hole. 

What you say / write at any given time is based on who you are and how you perceive the world at that time. No more. No less.

Deleting stuff is an act of cowardice. It's easier to delete than to say "I was wrong. I have changed and this is my new take on XYZ".

Holding people hostage for what they wrote 10 - 15 years ago is at the very least childish and more often than not evil, based on certain agenda and an ill will.
