I look forward to the day that I can look and say xyz is wrong. Right now they look fine to me but given your title I know I am 100 percent incorrect. Still learning.
Everything is wrong!

I would call them "dangerously aggressive".
Not the greatest job, too much hook, and looks pretty inconsistent as ti where he held his file, but if they cut. 
wonder if he was even using the right sized file, some of the cutters look like it was too small a file the way he's dug into near the gullet area.

I'm sure we've all seen far worse. Could be better yes, but I know people who could have screwed it up much worse. If the corners look good, that's what matters most, and as far as depth drags go, that's totally dependent on species and powerhead size, none of which you mentioned. 70 cc in Cedar isn't 50 cc in Hard Maple.
That’s what you get when someone doesn’t know how to run a grinder. The ol’ angled J.
Just like a file, a grinder shouldn’t hit everything from the top of the tooth to the tie strap in a single pass

So when you say too much hook. It is too grooved out? So probably too small if a file sharpening it?Not the greatest job, too much hook, and looks pretty inconsistent as ti where he held his file, but if they cut.
The grinding edge of the wheel should have a round profile to it. Just like a file. It’s pretty good advice if you only sharpen with that rounded portion of the wheel. If you go too deep, you are grinding with the side of the wheel, as in the OP’s pics. When you do that, it leaves the angled J shape I referred to earlier, rather than a C or ( shape
Old "get the gullet" crowd.
Don’t see a problem ?
Looks like they used the wrong wheel. Probably 3/8 Picco instead of .325/3/8
Never even thought it could have been a grinder, but yeah that would make perfect sense.
Those chains on an 066 would absolutely rip softwood species of wood to pieces. If the powerhead has the power a chain can be adjusted to the species of wood being harvested. Someone with the hours under their belt will sharpen a chain to suit both his powerhead and the species and size of wood he is dealing with and often that chain will not resemble a stock chain at all, and all manufacturers recommendations are thrown out the window.
1/4”, 3/8p, and .325 use the same 1/8”wheel. 3/8 and .404 use a 3/16 wheel. Larger chain can be sharpened with thinner wheels if the guy knows what he’s doing. In this case, it’s the Indian, not the arrow
Can’t tell if you’re yelling or if you accidentally got the black paint all over your fingers again
Same with files.......
Bold fresh taste!Can’t tell if you’re yelling or if you accidentally got the black paint all over your fingers again
