Couldn’t a Chromium clone relicensed under some copyleft license also be a viable option against Chromiums? Chromium is licensed under BSD-3 which Wikipedia claims is compatible with the GPL, so there wouldn’t be any legal reason this couldn’t be done, right? Other than not really wanting to split a project with excessive forks (which is only bad if you think that the Chromium project itself is a net good), is there some technical or other reason why this would be a bad idea?
