Can't you just right click?

This makes me wonder how open source is supposed to work on macOS. People seem to become more and more aware of it and even enterprises that insisted on support contracts can see that they can't get around open source completely anymore. Meanwhile Apple is removing the ability for me to have a pet project without paying an Apple tax.

If the message were completely transparent, something like "The developer didn't pay $99 for us to do a cursory check on them (or whatever it is that Apple does with that money), are you sure you want to run their software? [Move to trash] [No] [?]", then that would give the user the relevant information to make this decision, but as it is, virtually no mac user will understand what is really going on.

I also can't imagine $100 is easy to come up with in countries below level 4[1]. The OpenStreetMap Foundation recently introduced a way to waive the yearly £15 fee for OSMF membership if you have a certain number of map edits or otherwise contributed to the project. The OSM community seems to be quite diverse, but I can't imagine that Apple computers are less widespread than OpenStreetMap.

Can't you just [give up on macos as a general computing platform]

This feature is at about the right spot for me.

It is still convenient enough for me to run software I want that isn't signed, but sufficiently obtuse that neither of my parents have figured it out. Given they are both prone to running any executable that any website tells them to download and run, this feature has probably save me several dozen hours of fixing their computers.

But then you’ll have websites that walk you through changing the setting. At least this way you have to make a decision every time, even if it costs you a few clicks each time you do it.

The fact that the standard model of computing is that applications are opaque machine code blobs that can access everything in your user permission space is the core problem in privacy and malware. Applications should see nothing but their executable jail, and whatever was intentionally allowed to them by the user (eg, Open file dialog giving the application an opaque file handle, etc, not carte blanche access to the entire filesystem). Ideally, the notion of machine code blobs should be done away with as well.

Mobile OSes got to rethink everything in an era of constant adversarial connectivity and started off on a better foot in this regard.
