What’s wrong with Ian again?
Nothing, really.
It's mostly 1) jealousy, 2) very tenuous claims about his political leanings, business practices or other perceived slights or 3) minions from karl's gae commune.
To me he strikes a good balance between surface level and detail (he has and still does go into detail and covers more than an overview, but that gets brushed aside I think sometimes by comparing it to other content that's 2hrs+ of fannying about on sling swivel screws or the thread used for stitching some crappy .32 blowback service pistol used by some backwater country at the arse end of WW1.)
Can't deny his work ethics, certainly seems to invest a lot of time and effort even after quite a few years, glad for him it seems to pay off. And seems to be a pretty decent guy what can be judged from a far (i.e. not corrupted by fame or other idiocy).
Stays mainly on the technical side, relates to production and manufacturing. Overall a good ambassador for firearms related content, if you showed his videos to a Euro you might interest them and not have them report you to Von der Lying.
Only actual genuine reason ive seen people dislike Ian over is the Rock Island Auction thing IF its real(supposedly got his famas by cutting out the auction and went straight to the seller, got his seller info from RIA).
Rest of the reasons ive seen have been mostly autistic, such as:
Wasn't that Larry Vickers' Famas?
I wonder if that's why he doesn't make videos on their guns any more? And did they blackball him with all of the other auction houses as well? I seem to recall he'd do guns at several auctions but they all seemed to stop at around about the same time.
From what I remember from that period what Ian himself wrote about it when asked was that RIA wanted more control over his video's/content and that was not something he was okay with. They seemed to have gone their separate ways on good terms. Didn't see any snide remarks from RIA or anything along those lines.
He only did video's at RIA and James D. Julia as far as I can remember. James D. Julia is now Morphy's and he's still good with them judging by the videos from last year/this year. John Keene still a guest from time to time (talking about audio issues, does that guy have a voice that's somehow incompatible with audio recording equipment?)
