I think it is to early to say. On the one hand, BRC-20 uses bitcoin so in that sense they are increasing adoption. But the question I think you are asking is this TYPE of adoption good for bitcoin growth. I don't think higher fees are gonna hurt adoption long term but short term it may. Who knows. Honestly, I don't see the value of this stuff... yet. I try to be open minded and I haven't looked into it deeply. So far from what I've seen it is a waste of time.
