Switching to Git makes sense, but choosing GitHub is diametrically opposed to what Mozilla claim their principles are — specifically principle 6 of the Mozilla Manifesto: “The effectiveness of the internet as a public resource depends upon interoperability (protocols, data formats, content), innovation and decentralised participation worldwide.” => https://www.mozilla.org/en-GB/about/manifesto/ https://www.mozilla.org/en-GB/about/manifesto/ In future it won't be possible to contribute to Firefox without a Microsoft account. If Microsoft decide to close your account (which they're entitled to do — they own the website), you can't participate. Mozilla were one of the few hold-outs against this particular attempted monopoly. Again, Mozilla makes a short-termist decision that makes sense for a Silicon Valley lifestyle brand, but makes no sense for an independent mission-driven public-service community project. They're an untrustworthy upstream.
