I don't think I fully grasp what you mean by "compromising the blockchain integrity" nor how did the big blockers threaten that.
big blocks -> blockchain grows faster -> more space required sooner -> higher costs to running a node -> less nodes -> more centralization -> less censorship resistant -> more potential for forks -> more potential for compromise of blockchain integrity
Ordinals or BRC20 do none of that. On the contrary: they contribute to the security budget
