I agree, but aside from a couple edge cases (again avoiding spoilers) I'm not sure I'd categorize any of them as particularly villainous. That show does a good job of showing broken humans as the complex messes they really are. And yes, Apple gear is everywhere in seemingly every frame of it.
Yes, but the other Apple Originals I've watched don't have much if any product placement. Granted it would be anachronistic in something like "For All Mankind", but I don't recall seeing any in "See" or whatever other shows of theirs I've watched either.
The product placement is quite deliberate and to be expected, even though Apple probably thought it was clever and subliminal e.g. if you are an iPhone owner, and use the default note/tri-tone/chord ringtones, you will be reaching for your phone at least once during The Morning Show.
On a slight tangent, in my opinion, the best recent representation of phones and villians, was is in the now cancelled show: Ray Donovan; you can spot everything from old school fliphones, Blackberry's, Lumia, iPhones et al. in it's seven series trajectory. Furthermore, somebody on that show is also a watch-nut and likes cars!
