I'm still struggling to understand the "why."
(That's not an implicit criticism of the article, which is extremely appreciated because it's neutral and factual)
I've been away from Ruby for a few years but Shopify always seemed like a huge net positive, sponsoring lots of valuable work on both Ruby and Rails. I never followed Ruby community happenings very closely but I'm not aware of negative feelings towards their community role in the past.
Apparently, the reason is having an incorrect opinion.
