If v30 gets released and opens op-return to anything. Do you really believe people won't put malicious JPEGs in there just to paint bitcoin in a negative light?

If they do, do you think there will be more or less full nodes in 5-10 years?

If bitcoins full node count isnt going up, but going down, is it safe to say that bitcoins protocol is becoming less decentralized and therefore... failing over time?

How can a protocol gain the economic trust of individuals when it is slowly failing?

And I do think, yes, bitcoin will still work, this won't do anything from a technical standpoint. It will only hurt the incentive to run a full node.
