The author did make it unavailable. Nobody forced him to. He's kneecapping his own content and intentionally excluding UK users unnecessarily.
Some random developer blog is absolutely not the target of the Online Safety Act. The OSA applies to "services with a significant number of UK users or where UK users are a target market".
Anyone arguing that point is doing so in bad faith, probably to prove some agenda.
I've put considerable time into this, including speaking with Ofcom directly. The guidance Ofcom issued for small site operators last year was that they did intend to target "one-man bands", and that there would be no guidance on specific numbers that constituted the "significant number" of UK visitors which triggers Part 3 and 5 provider restrictions.
