I'm quite confused after reading this and seeing the list of websites where he was providing "free resources". At first I thought it'd be unlikely that a free resource would fall under one of the categories where the accessibility law applies (closest thing would be the educational services sector, which I don't think applies here) but I thought, well, maybe he's just being careful?
But what stroke me ad odd, other than never hearing about these free resources in Hebrew (my mother tongue), is that it seems odd for free resource provider to have _so many domain names_ in any language, but Hebrew in particular (.co.il domain names are expensive and Hebrew speakers is quite small even if you don't deduct those who feel comfortable studying in English).
So I clicked few of the links which by now redirect back from each of the the domain names to https://lifemichael.com/corporate/ where he offers his courses (which are not for free, not that there's any issue with that).
But I wanted to take a look what he offered in the past though these websites and plugging them into archive.org I found that each of them seemed to have served identical content, which prometes his non-free courses, including in-person courses (it's in Hebrew but it's easy to see that it seems identical even if you can't read the language):

I see that he does have a youtube channel with free content though. It's in Enlish and I'm pretty sure there's no ground for the accessibility law to bite here (though I have no authority to skay so): https://www.youtube.com/c/lifemichael
At any rate, this post makes little sense to me in the context of free online resources as being subject to the Israeli accessibility law, and IMO the author does little to none in leading the reader to any other conclusion.
Since the websites he removed were mostly offering paid services, they may have been subject to the accessibility law is my guess.
