The man in charge of this (/u/bencredible on reddit) has also explicitly stated that it's not intentional.
A dodgy SpaceX landing means a) ship and b) three engine burn.
The ship feeds have always been sensitive to vibration - they've cut out every single time - and three engines makes significantly more vibration.
You can conspiracy theorize if you want, but it's a bit like complaining that there are more photos of the outside of the White House than the inside of the President's secret bunker.
Maybe you haven't seen some of the earlier ones that had RUD. Take this[1] one for instance from the SpaceX channel. Looks like they stopped using helicopters to stream the landing. Makes sense, because once you have all the kinks worked out, you no longer need redundant instrumentation.

Edit: Adding a successful one[2]. See how the rocket comes in, pointing away from the barge and then straightens up.
It does look like there's a "PR filter" in the video stream and it kicks in when the landing looks iff-ish.
This makes perfect sense too if you think about it. If they were to crash yesterday and there were a video cap to go with it, it would've been all over news in no time. But with no visuals the news like this are far less likely to be reported, leave alone to go viral.
It's not about withholding the footage, it's about releasing it in a controlled fashion.
Now do it on a boat, trying to compensate for waves and exhaust gases from a 27.4 tonne rocket.
