Given that the training approach was open sourced, their claim can be independently verified. Huggingface is currently doing that with Open R1, so hopefully we will get a concrete answer to whether these accusations are merited or not.
Even if the Ryzen wins out, that would still be comparing a desktop CPU to a mobile one, using 105W vs 10W. It is incredible that we are making these comparisons. Apple outdid themselves.
I would argue Apple is very protectful of their platform, at the expense of the users. Of course in some cases, such as with privacy, what is good for the user is also good for Apple, because they get an additional selling point compared to the competition.
In my opinion, an example of Apple practices which are bad for customers is their line on progressive web apps. Apple limits support as they cannot keep control of their platform and revenue stream. I would argue however, that installable web apps are great for user experience, especially since it helps less resourceful businesses provide a good product for mobile devices. I'll admit there are privacy concerns regarding access to phone features from a web app, so Apple's arguments in blocking some (but not all) of these have some merit.
If you look beyond just the App Store policies, this general practice appears to me to limit innovation on the web platform, as Apple is invested in keeping apps the only first class citizen on their platform.
Except if that data is shared with third-parties for profit. Then the data may be useful to them even if you are not logged on. Since they also track you from any other page that uses their API / share buttons, this "worth" does not necessarily decrease regardless of usage. You also cannot easily (or at all) revoke these third-parties' access to your data.
Add to that the risk of them not providing good enough security regarding access to the data (such as with the Cambridge Analytica case), and giving them access to so much of your data becomes an additional problem to consider, since you have no control over that data sharing whatsoever.
