I would agree that people are giving Medvednikov an unreasonably hard time if he learned from his mistakes, but everyone kept bringing up his past anyway.

But it just seems like Medvednikov keeps repeating the same patterns over and over. He's making dubious claims about software without sharing how he arrived at those claims, and he's calling something open-source when he hasn't released the source.

Why should people who know about this pattern stay silent and allow others to be misled by the same patterns?
