She's clearly making a substantial amount of money from her YouTube videos, nearly 7M subscribers is pretty darn impressive no matter what you think about her. And she posts much more than Apple reviews.
I haven't watched that many of her reviews, I do enjoy her enthusiasm, and it seems to me that I have heard her comment on more than one occasion that she would be returning the products she was reviewing, so at least in some cases I take that to mean that she gets sent promotional products for the purpose of review and then has to return them (to Apple, in particular). She is clearly not buying every color iMac, for example, or every Apple Watch olympic band, but she gets them all and then does the unboxing and comparison, and then oftentimes you don't see anything further posted to those products.
With that said I also have seen one video of hers where she is going through the cabinets she has set up to organize all of the iPhone cases, and battery or charging products, cables, things like that, so some things are clearly provided to her for review and then she does not have to return them. The difference may be how Apple itself handles these products they provide to certain reviewers, and how other companies handle them.
(This is largly a general rant about reviews and reviewers, and the potential for them being something worse than meaningless) I was alive in the 'payola scandal' times. The radio station I worked at was involved in that mess. You played what you were paid to play, and you gave it the best reviews you could. Yeah, it sucked.
I am serious in the bike industry (and prior to that was int he IT industry for around 40 years), and the 'turd polish' from some reviewers is epic. Some reviewers are just about as close to useless as useless can be. One guy, I respect, published a brutal review. In it, he said that he was likely to never get a pre-release sample of their product ever again, but he could not hold back on his disappointment of how bad the product was. He kept stating that it was 'pre-release' and would likely be better, but in the end said that he 'hoped' it would be better. The company told him he was safe. They 'valued his, and other inputs', and did delay the product. What was embarrassing was all of the 'other reviews' that were glowing to the point of being blinding. They obviously were 'sucking up'. One that I really trust does get some units to review as pre-release units, but also buys them from local dealers, and has compared them. Most of his reviews are from items he buys himself.
I've been alive, and in both industries long enough to know that there are people who will pad their opinions because they want to get new toys to play with, and fear that if they give a real honest review they will be banned.
It's got to be a problem. On the one had, you get toys, you get 'access', you get attention, and on the other, you risk throwing it all away.
NOTE: I am NOT saying she is 'bought', but, for me, I prefer to get what I think to be 'honest' reviews of 'real' products that I could end up buying.
Suspicious? Heck yeah! I hated having to deal with the rumors of payola continuing at that station. I felt humiliated just thinking of what happened there, and at so many other stations across the country. I have always tried, in my reviews to clients, to be honest, and not BS them. If it's something I wouldn't use, I freely told people that, and why.
*shrug*
The rant is over.
I value the reviews and opinions from MacRumors, and its members, and search for, if needed, reviews on other things. It's tough to find meaningful and honest reviews out there. For those that are out there, hats off. Bless you... Again, no opinion on her. I just have a hard time taking her serious.
