@matt @mauro @anthropy Proprietary software is less of an issue for the health of an ecosystem than a monoculture. Opera/Presto was a net positive for the health of the web because it was an independent implementation of the W3C standards. Google's control of the WHATWG via Chromium and the controlled opposition of Gecko is catastrophic: the Blink code being open source is completely irrelevant when whatever Google decides (and nothing else) goes.
