the mechanics of ICs are interesting, but how often do people actually do chain grab combos like the one in the gif? in most tournaments you just see typical wobbling / plain back and forth chain grabs. and with regard to the, "don't get grabbed".. it's dumb. if you don't want to get grabbed, it forces you to play on platforms more than you usually would, slowing down the pace of the game.

even in the beginning, you can clearly see m2k is trying to avoid being grabbed by avoiding the ground completely, going back to the platform as a safe jump reset, but at 1:20, he gets grabbed. what are you going to tell him? don't get grabbed? smash is a game where you play off peoples mistakes and capitalize on them. MAJORITY of the time, it's impossible to be perfect, otherwise you'd see jv 4/5 stocks a lot.
