Someone can fork chromium if need be. There are at least a couple organizations with chromium-based browsers that have maintained their own engines in the past. Chromium is objectively very good so it’s not like it’s the time when we were left with IE5. The biggest problem now is Google trying to protect their ad business and the other Chromium browsers have been working around that. I don’t think we are nearly as bad off as we have at other times in the past.
