It will be interesting to see whether this is a 'real' boycott, or simply a convenient excuse for cutting ad spend. Alphabet (Google) is probably the most comparable company in terms of revenue sources, and their earnings were down 20% YoY for the first quarter. If Google's revenue is down by more than 20% as of their next report (by end of July), I think we can firmly say that the 'boycott' is just showmanship. I suspect this is the case, given the low fill rate for ad slots on Youtube right now.
