Just read the law. It is barely 1000 words.

But still, this law as is applies to computers, phones… And nas, some routers, watches, advance calculators… As they all have OS and can install apps.

No. It specifically only applies to general purpose computing devices which means all of the items you listed after computers and phones are not affected. Can you hook up a monitor to your NAS without involving a soldering board and some additional hardware? Your router? Then it’s not general purpose computing. They both require additional computers to interface with them to be used. ‘General purpose computing device’ has been referred in prior legal documents to mean:

“means any general purpose computing device (e.g. server product, personal computer, desktop, laptop, netbook, slate or tablet), including any device that is designed as, marketed as, or capable (through docking or otherwise) of performing the functions of, such general purpose computing devices, and any replacement for any of the foregoing.”

© “Application” means a software application that may be run or directed by a user on a computer, a mobile device, or any other general purpose computing device that can access a covered application store or download an application.

(e) (1) “Covered application store” means a publicly available internet website, software application, online service, or platform that distributes and facilitates the download of applications from third-party developers to users of a computer, a mobile device, or any other general purpose computing that can access a covered application store or can download an application.

You then go on to complain about it affecting FOSS stores? That’s exactly my complaint. Who are you convincing here?

Jellyfin, Docker, git??

(2) “Covered application store” does not mean an online service or platform that distributes extensions, plug-ins, add-ons, or other software applications that run exclusively within a separate host application.

No.
