"I'm in Europe so I don't have to care because software patents are not enforceable here" isn't the solution. Yes, patent law doesn't apply - but copyright law does, and they very much can take down content that references the spec just based on copyright law alone.

In a lot of european countries there's specific legislation allowing computing interop that overrides copyright. Eg https://eur-lex.europa.eu/EN/legal-content/summary/computer-...

(Also I'd think copyright in EU doesn't normally apply to implementing protocols as it's supposed to grant monopolies of creative expression? but IANAL)
