That attitude is exactly the problem. Shopify does not 'keep the ship afloat' they are just a corporation using open source systems as the foundation of their business. Competition is not by definition the backing of a 'conflict of interest', it legally refers to a person or entity with a stake in a particular outcome having control of the means to achieve that which are not legally sound , ie compromise their judgment. I think Shopify's judgement of what 'is good for the Ruby community' is severely compromised by their corporate interests, and probably by their boards political interests as well. Hence, why they are trying so hard to justify removing Andre.
Do you have any idea how expensive it is to keep the infrastructure running? RubyCentral's operating expenses are in the millions every year and exceed their revenue.
Andre's removal is easily justifiable by his own (lengthy history of) sketchy behavior.
Since when is "open source" something businesses shouldn't be allowed to get value from or even have a stake in? These things are MIT licensed. That's free as in speech AND beer. If you don't like the freedoms of the license and how other people use them, don't use the license. If you don't like someone's stewardship, fork and maintain your own.
