How will this law effect Linux?

Germany passed a law, officially for child protection (https://www.heise.de/en/news/Minors-protection-State-leaders-mandate-filters-for-operating-systems-10199455.html). While windows and MacOS will clearly implement the filter, I can't imagine, that Linux Devs will gaf about this. Technically, it should be possible to implement it in the kernel, so that all distributions will receive it, but I don't think, that there is any reason for the Linux foundation to do so. Germany can't ban Linux, because of it's economical value, also penaltys for the Linux foundation are very unlikely. But I didn't found any specific information on how this law will effect open source OSes and I'm slightly worried, that this will have an effect to Linux.

What are your opinions on that?
