It’s open source. You can even build it yourself it you want to

It’s not open source, it lacks a license entirely. And, therefore, nobody is allowed to build it themselves.

You can sure build it, if you want to. And the source is open, so you can check it out.

But sure, I’ll cave. What would be a better term for this?

> You can sure build it, if you want to.

I am physically able, yes, but I am not legally allowed to. Since I am not given any permission (i.e. license) to do that.

> And the source is open, so you can check it out.

The term “open source” is used in two ways: the intelligence community reportedly uses it to refer to information sources which are publicly available, as opposed to secretly gathered information. The other use of the term “open source” is as defined by the OSI, who pioneered this new use.

The usual term for source code which is merely available for reading, and not much, if anything, else, is “source-available”¹.

We agree, then :) If they’re anxious regarding the privacy implications of using this extension, they can build it themselves.

> The term …

Alright, I agree, that was a misuse of the definition on my part, and I should have said “Source-available”. I was unaware of this definition, so thanks!

Source available?

Nice, thanks! Didn’t know that one.

I'm pretty sure it doesn't work that way, Apple let you register URLs to redirect to your app, so I'm assuming they've just done this for AMP URLs and strip it back to a proper link and then open that using the system browser (whichever you have set).

No, this is the new Safari extensions API in iOS 15.
