Yeah, no. He almost entirely verbatim copied the text and wording on the original article and shuffled some words around to try and make it less obvious (and failed). It is blatant plagiarism, there is no other way to call it. This was no innocent mistake of forgetting to list a source. Watch the hbomberguy video segment about it, it paints a very clear picture.
You may want to look into Shelly relays. You wire them to the physical switch in the wall and can control them locally with Home Assistant or just individually via WiFi. Only downside for most folks (especially in the US it seems) is that they generally require a neutral wire to work.
It is probably way too late for that to make any difference, no?

It's called that because 20 years ago when the guide was first written there was no Gmail or any comparable service of that magnitude. Sure you had GMX or Hotmail but most people online back then had an email account hosted by their ISP. That was the most common way to get access to email.
The ISP Mail guide describes how to set up a mail server infrastructure similar to what an ISP mail service would provide, back then.
The Home Assistant blog covered the whole thing very well: https://www.home-assistant.io/blog/2023/11/06/removal-of-myq-integration/
Slander?! I resent that. In print its libel.
