For your use case, building from source might be more practical.

Why the hell do you only have 8GB? Are you trying to install flatpaks on a smart fridge?

Anger has a way of adding a few zeros.

I get why Federation can cause issues (most of the time it’s moderation related), but why would an extra option be a deal-breaker? Federation can always be disabled on a per-domain basis if you prefer. In fact, I’d argue it’s best practice to only allow domains on a case-by-case basis to prevent spam and abuse.

On the converse, you can’t enable Federation on a platform that doesn’t have it.

Yes, which is good, but the lack of federation is a deal-breaker. It means that you either:

1. Use their servers - This requires entrusting them with your communities, just like Discord.
2. Host your own private instance - You can control it, but the lack of federation means it’ll be isolated from communicating with other communities. This makes it really difficult to convince people to use your self-hosted servers.

Until Revolt adds a way for different instances to federate, Matrix is really the only other option.
