And if they do start putting ads in video streams then I will likely be writing them off for dead just like I did months ago with Reddit. Til then I'll be using the various moles that still haven't been whacked (there's a good few) and not suffering through the experience. If they think they're getting a dime from me with the agenda they push, just because the creators I want to see don't have time to post across the variety of platforms (yet), they can get their heads examined.
