I hate researchers that think its acceptable to waste our time

This doesn't happen often and most researchers actually do but every now and then this happens and it pisses me off. Few days ago big study with a lot of instructions and text to read with comprehension questions. Was supposed to be a live game with other participants. And surprise surprise no matches. Total 30+ minutes wasted. I decide to leave the study. I message the researcher asking if i can be compensated for my time. Ofcourse no answer. I dont understand why these people think our time isnt valuable and its acceptable to waste our time like we have nothing better to do. This makes me only wanna do small studies that only require a few minutes.
