No, that isn't how it works. Miners can't flood blocks with ordinals without losing money in the long run. Imagine winning a 6 bitcoin block reward and spending 3 bitcoin to fill the block with garbage. The energy costs and miner costs would go into the red, unsustainable.

Writing ordinals has been possible for years, but with Twitter you get a lot of idiots that think it's cool, so you get a passing fad.
