The definition of application is so broad that it seems to cover any kind of software, even if it does not actually interact with a user, but merely provides system functionality (like your network device discovery daemon e.g. bonjour/avahi, or device drivers) just because you can download it.

Any software you can retrieve from the Internet and "launch" is required to collect user age data. Like your graphics card settings app, your PDF reader, a calculator. I can't figure out what they're supposed to do with it though, so it's a lot of work for no reason.

WTF is "launch" supposed to mean? Install? Open?

I guess every little toy app I put on GitHub is now going to be subject to this? If I fork an old application that doesn't provide the interface, am I now responsible for doing so even if I only use it on my own devices?

What about software developer by people that aren't in California and don't want to be bothered? Can I now not use their calculator or spreadsheet or text editor applications because they don't collect age verification signals?

2027 is way too soon because there's no way all the Operating Systems have decided on the shapes of their signals, so I can't even start figuring out how to implement in any of the 5 programming languages I have used to develop apps.
