If you don’t want to see flags, don’t participate.

Or alternatively we [people who don't want to see larger flags seizing the space that should be taken by more meaningful stuff] can gather support to fight back within the rules of the Canvas, even if you found such a polite way to rephrase "if you don't like what we do, fuck off and don't play".

And I'm not even saying here "don't post flags at all". I'm saying "cut the larger flags down to size".

country flags have their place on there just as much as the endless brand logos, ponies and amongus crewmates.

And if left alone, their "place" becomes the whole canvas. We all know how nationalists are like - give them a hand and they'll scream "THE WHOLE ARM IS MY REICH".

Limiting the template regardless of what's being drawn is an idea worth discussing with the devs.

Oh wow. I had to go back to check for the Australian flag. Took me a bit to notice the blue and the two stars around the British Flag.

I’m satisfied with how things turned out, with art going all over the flag and the stars shining through, but it didn’t seem considerate in the beginning.

It's often like this, to give you a false impression of a compromise. I've seen it all the time in r/place, for example. (Doubly true in pixelplanet, but that's... eh, let's say that biggest drawing there is a swastika.)

And typically, it goes like this:

1. Claim a huge space of the canvas for the sake of the flag.
2. Lay waste over whatever is in the middle of the way, be it drawings or flags from other herds.
3. "Oh fuck, it's too big for us to defend. People are drawing random stuff over it."
4. Eventually let the people drawing random stuff to do it, under the terms dictated by the flag itself. Under a discourse that sounds a lot like "this is the land of Our Holy Symbol. However, since we're magnanimous, we shall turn a blind eye to your doodle defacing it."
5. [If applicable] Shift the blame of the step #2 on others. "Nooo, I didn't do it. Others did."

Besides the façade of compromise, there's also a second motivation for fourth last step: it's a way to co-opt people drawing random stuff to protect the flag, as they likely care about the surroundings of their own drawings.

Please do note, however, that people drawing those large flags do not want to reach an actual compromise. And playing nice (cooperation) only works if the other side is also playing nice - we shouldn't be playing dove in a hawk-dove game.

Will you organise a Matrix chat for this?

Now I will - that's a great idea.

I'm planning to do so when the next Canvas is announced, in 2025, as people will be a bit more pumped up to join than now. (For now I'm mostly gauging interest on the idea.)

When I do it, do you want me to ping you?

That flaw is an issue, indeed. And it's worth thinking on ways to reduce it.

However, there are two things in our side:

1. the proportion of people holding critic and informed views about flags on Canvas is likely way higher than in r/place.
2. due to the nature of the symbol in question (country flags), herds of "large-flaggers" will likely have trouble coordinating with each other.

Ultimately, flags are just symbols similar to any other logo.

Emphasis mine. I get your reasoning here and I agree with it; it's just that those specific symbols are egregiously problematic in this sort of "collab+compete Paint simulator".

Sorry for the double reply. Another thing that I realised in the meantime is that people working on flags won't be willing to divert time too much time to undo defacement of another flag. So as long as we concentrate our efforts towards a single flag, the opposition of other flag-posters will be spotty at best.

could we incorporate artwork over the flag like it happened with the Australian flag?

My main idea is to deface the flag, so I'd ask people to not integrate the artwork. But if you do integrate the artwork I'd ask people to leave it alone and focus on the flag itself, so it would be safe.
