Since you are not playing freerolls, you are probably playing hyper turbo with shallow stacks and fast structure, right?
If that is the case, going all-in or folding is perfectly normal since most of it starts with 10bb, and you do not have any room for postflop play either way. This is mathematically based push fold chart, so take a look at it and see what hands you should be shoving yourself and when.
If you are not playing hyper-turbo format and still see players moving all-in every hand in standard structure, just let me know where these games are, and I am heading that way! :)
If you want to play more REAL poker, simply play slower structure games, and you will surely have enough room to try your moves.
