WebKit is open source but Safari isn't meanwhile Chromium is. WebKit is sometimes a bit closed until it reaches embargo that Apple sets. But anyway Safari is good to web diversity.

I never said Safari was open source.

What I did say is that Chromium was based on WebKit and then a fork of WebKit, blink.

Let’s not credit Google for Chromium without recognizing that it was Apple’s open source work that made it possible.

To suggest that WebKit isn’t open makes no sense at all. It may not have a governance model or development processes people like, but the fact that the source is open and has been used to build competitor products and has been forked means that it is unquestionably open source.

Nobody suggested that Webkit isn't open. You have a nasty habit of putting words into other people's mouths.

It seems like you agree with the person you originally responded to, who noted that Chromium is an open source browser, and Safari is not.

“Nobody suggested that Webkit isn't open.”

Yes, they did:

“WebKit is sometimes a bit closed until it reaches embargo that Apple sets.”
