Ok, I watched the whole match, and this is what I found: TL,DR version: Blue player (David Serdaroglu) was doing hidden serves so illegal they were being called (including by the ref off screen on the final point). He lost 8 points total in the match. Went ballistic more than once. Red carded after his final tantrum.
====================
Why am I interested? I'd very much like to see the rules either followed by the refs, or rewritten to be consistent with what is actually called in matches. E.g. Even though blue guy only lost 8 points to illegal serves, he is clearly in violation of this rule on every service:
2.6.5 As soon as the ball has been projected, the server’s free arm and hand shall be removed from the space between the ball and the net.
He's pulling the arm away at the last moment every time. Also I wanted to see if my speculations above were right [partially].
Detailed narrative of the match (this is the TL part
:
Very first point, and the red player is warned for his service - I believe warned for a non-vertical toss, which, imo is ridiculous: compared to _many_ serve tosses in the ITTF it was extremely vertical. Perhaps the refs knew there were going to be legal service problems in this match.
Blue player warned here in the second game:

Ref indicates the arm was not moved out quickly enough (I think). And we can see that the 'look-away' execution of the serve is his normal motion - so that wasn't a special thing he did on match point [so I was wrong in my speculation above].
Illegal serve called here - first point awarded:

Later that game, red player complaining about illegal serve here - not called:

This one is identical to his last serve in the match - not called:
https://youtu.be/yOPlwYWTrEQ?t=215
and the red player complains and starts talking to the ref off screen to the left.
Keep watching the next point, and you can hear the ref off screen say "stop" on the let serve and awards the point to Red. I think the off screen ref is the heavy set guy in the suit and blue shirt we see at times. Long "discussion" about the serve, and probably the ref making that call from off court (I don't know the rules of that league, but it is a valid question). The match almost ends here I think. Blue deserved a yellow card.
Video editor speeds things up here - minutes pass for sure.
Another repeat here:
https://youtu.be/yOPlwYWTrEQ?t=436
Red player complaining he can't see the contact - [I agree btw - and clearly it's not the arm on this serve, but the body blocking the view].
Next point - same thing - hidden serve for an ace this time. You can see the red player not even reacting because he can't see the contact.
Here they correctly call it (but this time it is the arm too blocking the view):

Another illegal serve called here:
https://youtu.be/yOPlwYWTrEQ?t=576
The next serve is _almost_ identical, yet somehow not called.
Another clearly illegal serve, but not called:
https://youtu.be/yOPlwYWTrEQ?t=605
This one is called:
https://youtu.be/yOPlwYWTrEQ?t=686
You can hear the red player as he comes toward the camera, saying "This is incredible. I don't see nothing." Meaning he can't see the contact at all.
Late in the 5th game, another one called here:
https://youtu.be/yOPlwYWTrEQ?t=738
Again the video editor speeds things up. Blue guy throws his racquet on the table, into the net. Eventually gets a yellow card.
Another not called here to get him to match point 10-9:
https://youtu.be/yOPlwYWTrEQ?t=788
Then the last illegal serve:
https://youtu.be/yOPlwYWTrEQ?t=795
We hear the off screen ref say "stop" (I think) as the serve hits the far end of the table. Note how the red player can't even react to this one. Blue player then goes nuts, jumps on the table [I would ban him for a while from my club for that alone], rips off shirt. Also note that the scorekeeper ref indicates his uncertainty about who should get the point - I don't think either on court refs realize the off screen has made another illegal service call. Red player is pointing at the off screen ref. Head ref on court looks over and changes the call, making it 10-10. But blue doesn't come back to play, storms around. Off screen ref comes over behind the head ref, and think tells him to give the red card because of his histrionics. End of match.
Opinion: This all hinges on the consistent enforcement of the service rules as written - if there is any doubt the service is legal, the refs should be calling it. This guy shouldn't remotely be doing this motion in his serves. Samsonov has been doing great, non-hidden serves since hidden serves were legal - players and the sport don't need this hazy line controversy imo.
Cheers and to anyone that read this all, I hope [you] didn't find it boring
