On: Mozilla Firefox – Official GitHub repo

To assert that an organisation doesn't "truly" care about open source simply because they've chosen a tool that isn't is ridiculous.

Even before this Mozilla almost certainly used hundreds of closed source tools, including things like Slack, Excel, Anaplan, Workday, etc.

Using proprietary software in-house for management is one thing, forcing outside contributors to use them, another. That is why they went out of their way to avoid Slack when the time came to leave IRC behind and they chose Matrix instead.
