I agree, and most of my prof friends in math have switched from graded homework to weekly small quizzes. Graded homework was a way to use the stick as motivation because we've given up on the carrot (the learning of the material itself as an internal reward for completing homework).

Some of them keep the homework grade to like ~5% and mostly grade on completion because, when the student's homework proofs use advanced concepts and proof techniques not covered yet but their quizzes get sub-50 point F grades with barely coherent thoughts, it's a clear sign that they are not actually spending time using the resources the class has given them to work on the material.

It seems like all of them have given up on punishing students for it, largely because they're pretenure and the teaching part of tenure review here is primarily student evals drive (HINT: this is a MAJOR part of many broader problems). But to me it's kinda nuts that in one year or so, we have decided that it's actually ok to admit students into very competitive elite institutions, catch them passing off work that isn't theirs as theirs, and not treating that the exact same as we would have a few years ago if we caught them all sharing solutions.
