Cards get bent, participants can see who's chosen which before and where they get allocated, the research assistant is unblinded (could influence selection), shuffling is non-random and easily manipulable etc
Bent cards and other things that just change the relative weighting of the randomization isn't a big deal, as above. That impacts efficiency, but not bias. Non-blinding is frequently necessary and may not even be desired in all cases.
I don't have the rest of that paper, so no idea if the latter is reasonable, but the RCTs that I've done and been involved with have effectively no blinding very much intentionally.
