Does Matrix encryption scale? Telegram rooms have a huge number of participants. Also last time I looked into this, Matrix encryption was also an opt in.

In Matrix all PM rooms are E2EE by default.

For public rooms however, it doesn't really make sense to enable E2EE.

Many people seem to think that Telegram tries to be a Signal or Matrix replacement. I dont think Telegram tries to be any of that. If anything you can compare it to Discord, except much better.

To enable synched e2e conversations accross many devices you also need to synch private keys, which is a security nightmare.

Either sync private keys or the messages itself.

Why would it be a security nightmare? In contrast to not even supporting e2ee in the first place?

How would you securely sync priv keys? How would you securely sync plaintext messages?

Telegram supports e2ee but it is device centric for this reason

Same as with private keys: Verified e2ee

At least this is what they told you

About as meaningful as the suggestion to use "verified e2ee" to transmit private keys
