With all due respect, and I mean this totally neutrally...
Is there any way to get Citrea to just stop? Like hey, 'cut it out'?
Some of the criticisms I've heard are specifically that one company wants to make use of larger op_return data fields... so why change mempool policy for one company specifically? What if another company in the future wants to do something else, even if in the spirit of harm reduction, should we change mempool policy just for a company to play defi?
Another question: how many unprunable outputs are we talking about from Citrea? Hundreds? Thousands? Tens of thousands? Is this something really core to their business model? Is there any other way of them doing what they want to do, without requiring such a change? How polluting would they (or the others to follow them) really be for the network?
Finally, since LibreRelay works with only a limited number of nodes in the network available... why don't they just use LibreRelay? That way they could have larger op_returns without necessitating unprunable outputs.
THANK YOU
Why do you want them to stop?
They want to use Bitcoin and make an L2 on top of it.
No there is no way to make them stop with the current consensus rules and it's deeply pathological to even suggest such a thing. Bitcoin is supposed to be censorship resistant.

They need two taproot outputs to embed an extra 32bytes * 2 in.
So in total they're embedding 144 bytes of data.
This is also in the worst-case scenario that's never supposed to happen, where the bridge is malfunctioning.
In normal operation there won't be any data embedding here.

In this particular case, definitely not. Even with the "prove your bytes aren't arbitrary data" soft fork proposal they're doing something valuable enough to make grinding bytes feasible.
why don't they just use LibreRelay?
Because this type of Citrea transaction is time sensitive. Only two major mining pools mine oversized OP_Returns right now. That means there's a decent chance this type of Citrea transaction – a tx that responds to fraud – would fail to be mined.
